LACOVYL PVC PB1302 is a medium molecular weight polyvinyl chloride homopolymer resin produced by microsuspension polymerization for plastisol preparation. The product is specifically designed for the preparation of smooth-glossy compact coating layers at low or very low plasticizer levels, in systems with high fillers.
LACOVYL PVC PB1302 is a fine particle PVC grade that forms a paste, unlike classic suspension PVC molding resins. When mixed with appropriate plasticizers, it forms liquid PVC dispersias called plastisols; these plastisols can be used in coating, dipping, rotational molding, and various surface forming processes.
LACOVYL PVC PB1302 is usually supplied as a white, liquid powder or fine resin suitable for dispersion into liquid plasticizers. LACOVYL PVC PB1302 is thermoplastic and softens on heat rather than chemical crosslinking; this allows for recyclability and reprocessing. LACOVYL PVC PB1302 is insoluble in alcohol, but slightly soluble in tetrahydrofuran.
One of the primary technical specifications of LACOVYL PVC PB1302 is its K-value, which is approximately 70. According to the ISO 1628-2 method, its viscosity number is approximately 125 mL/g. This value indicates that the product is of the medium-high molecular weight PVC grade, creating a balanced profile between mechanical performance and plastisol processability.
LACOVYL PVC PB1302 has a very fine particle structure. This morphology can help to prepare thin coating layers more evenly, reducing surface defects and achieving high gloss. LACOVYL PVC PB1302 is a homopolymer polyvinyl chloride with a medium molecular weight.
LACOVYL PVC PB1302 is produced by the KEM ONE microsuspension polymerization process and is used in the preparation of plastizole pastes.
LACOVYL PVC PB1302, known as PVC for short, is the third most common plastic after polyethylene and polypropylene.
LACOVYL PVC PB1302 is used in the construction industry because it is more effective in pipe and profile applications compared to traditional materials such as copper, iron, or wood.
LACOVYL PVC PB1302 can be made softer and more flexible by adding plasticizing agents; the most commonly used are phthalates.
For this reason, it is also used in garment and upholstery fabrics, electrical cable insulation, inflatable products, and many applications where it serves as a rubber substitute.
Plastisols prepared with LACOVYL PVC PB1302 can exhibit very fluid character. Commercial product sources describe rheology from multifluid pseudoplastic to quasi-Newtonian behavior; the actual flow profile depends on the amount of plasticizer used, filler level and shear rate.
LACOVYL PVC PB1302 is particularly suitable for low-plasticizer formulations. Current product descriptions specify a plasticizing range of approximately 30–70 ph; however, this value does not imply a fixed recipe for each final product. LACOVYL PVC PB1302 can also be advantageous in high-fill plastisols. Its low pulp viscosity can help maintain workable viscosity in systems where high calcium carbonate or other mineral fillers are used.
LACOVYL PVC PB1302 can be used in saturation layer, back coating and other compact layers in floor coverings; in top and bottom coating layers in wall coverings; in PVC coated fabrics, sealing and sealing systems, dipping, coil coating and rod molding applications. LACOVYL PVC PB1302 is also positioned for use in automotive coated fabric systems due to its low fogging behavior. However, the final automotive fogging performance depends not only on the resin but also on all plasticizers, stabilizers and other additives used.
LACOVYL PVC PB1302 is not the final PVC compound. To obtain a processable plastisol or PVC product, the plasticizer, heat stabilizer, pigment, filler, defoamer, viscosity regulator and other application-dependent additives must be formulated separately.
WHAT IS LACOVYL PVC PB1302?
LACOVYL PVC PB1302 is a paste quality PVC homopolymer resin produced by microsuspension polymerization of vinyl chloride monomer.
LACOVYL PVC PB1302 is a polyvinyl chloride-based paste resin designed for plastisol and coating applications requiring controlled viscosity, good film formation, and mechanical stability.
Chemically, it is a high molecular weight vinyl polymer produced by emulsion or microsuspension polymerization; which results in a high surface area for fine particle size and efficient plasticizer absorption.
The polymer backbone consists of repeating –CH₂–CHCl– units that provide stiffness, chemical resistance, and good compatibility with common plasticizers and stabilizers. LACOVYL PVC PB1302 is compatible with pigments, fillers, stabilizers, and functional additives used in PVC compounding systems.
LACOVYL PVC PB1302 has good thermal stability up to 150°C and has much higher oil resistance than non-polar elastomers such as natural rubber or EPDFM.
LACOVYL PVC PB1302 is an industrial-grade polyvinyl chloride paste resin specifically designed for plastisol processing, surface coating, and flexible PVC product manufacturing.
It consists of long-chain vinyl chloride repeating units and forms a chemically inert thermoplastic polymer with high mechanical integrity and excellent strength.
The resin is produced using controlled emulsion or microsuspension polymerization; this results in homogeneous fine particles that ensure rapid plasticizer absorption and predictable gelation behavior.
LACOVYL PVC PB1302 exhibits low water absorption and good electrical insulation properties; these properties are beneficial for technical coatings and protective layers.
When plasticized correctly, the material maintains its flexibility and durability over a wide operating temperature range. From a processing perspective, PB1302 provides good flow behavior, low dust generation, and uniform dispersion in mixers and high-shear force mixing equipment.
It promotes stable viscosity development during storage and minimizes precipitation or phase separation in plastizol formulations.
Its compatibility with heat stabilizers, UV stabilizers, pigments, fillers, and functional additives ensures tailor-made performance for specific applications.
LACOVYL PVC PB1302 is usually supplied as a white, flowable powder with controlled particle size distribution and low residual monomer content.
In formulation chemistry, LACOVYL PVC PB1302 swells readily in plasticizers, forming stable plastisols with tunable rheology and gelling behavior. When heated, the PVC particles mix with the plasticizer phase and form a continuous thermoplastic film with good adhesion and flexibility.
This material exhibits good resistance to water, diluted acids, alkalis, oils, and many solvents; making it suitable for demanding industrial coatings and flexible products. The basic polymer of the product is polyvinyl chloride, i.e. PVC. The repeat unit of PVC is -(CH₂-CHCl). The general polymer formula can be represented as (C₂H₃Cl)n.
Since PVC is a polymer, there is no single, definitive molecular weight. The product contains molecular weight distribution consisting of different chain lengths.
Therefore, instead of molecular weight, the K-value and viscosity number for LACOVYL PVC PB1302 are used. The K-value is about 70. The viscosity number is about 125 mL/g.
These values are practical quality control parameters associated with the degree of polymerization and molecular weight.
LACOVYL PVC PB1302 is prepared by the microsuspension method. Very small polymer particles are formed in microsuspension PVC. When these particles are dispersed in the appropriate plasticizer, plastizole is formed. Plastizole is a liquid or paste-like dispersion at room temperature. The PVC resin does not dissolve completely at this stage. The particles are dispersed in the plasticizer. During heating, the plasticizer penetrates further into the PVC particles. Gelation develops first. At higher temperature, fusion continues. PVC particle boundaries disappear and a continuous plasticized PVC matrix is formed. This process forms the basis of plastizole technology.
The low plastisol viscosity of LACOVYL PVC PB1302 provides a significant advantage in coating processes. In high-speed coating applications, low and controlled viscosity can facilitate the production of a thin, homogeneous layer. Since the product may exhibit pseudoplastic character, the viscosity may decrease during cutting.
This behavior can be beneficial in processes such as doctor knife, roller coating, or high-speed spreading.
When shear is lost, the viscosity rises again, which can help limit filler or pigment precipitation.
However, PB1302 is also described in some sources as a very fluid degree close to the quasi-Newtonian character.
These two definitions are not contradictory. Plastizol rheology can vary with the level of plasticizer and formulation conditions.

CHEMICAL STRUCTURE AND MOLECULAR PROPERTIES OF LACKOVIL PVC PB1302
The basic chemical structure of LACOVYL PVC PB1302 is the polyvinyl chloride chain. The PVC chain is formed by the polymerization of the vinyl chloride monomer.
In each repeating unit, the chlorine atom is attached to the carbon backbone. This markedly increases the polarity of PVC on polyolefins instead of chlorine.
C-Cl bonds form stronger dipole interactions between chains. Therefore, pure PVC shows rigid thermoplastic character at room temperature.
The glass transition temperature of PVC is relatively high when no plasticizer is used. In plastizole technology, plasticizer molecules enter between PVC chains and reduce these interactions.
Chain mobility increases. The material becomes more flexible.
The molecular weight of LACOVYL PVC PB1302 is not directly indicated by an odd number.
K70 value is the practical definition regarding molecular size and solution viscosity.
Longer PVC chains create higher hydrodynamic resistance in solution.
This increases the viscosity number and K-value values.
PB1302 represents medium and high molecular weight PVC behavior with a viscosity number of approximately 125 mL/g.
However, molecular weight is not the only thing that determines pulp resin performance.
Particle morphology is critical.
In the process of microsuspension, very fine primary particles and their aggregates can be formed.
The contact of the plasticizer with the particle surface is affected by this structure.
Fine particles can provide an advantage in uniform film and surface development.
It also has the potential to increase the viscosity of plastisol.
The manufacturing design of PB1302 aims to combine fine particle structure with low plastisol viscosity.
Therefore, the product is valuable in systems with low plasticizer or high filler.
PVC particles disperse in the plasticizer at room temperature.
At the beginning of gelation, the plasticizer diffuses into the particle. The particles begin to swell. As the temperature increases, the particle boundaries weaken. At the end of the coalescence, a homogeneous plasticized PVC phase is formed.
The temperature and speed of this transition depend on the solvent power of the plasticizer used.
Classical general-purpose plasticizers such as DINP can be used as a reference in the technical characterization of PB1302.
Gelation can occur sooner when using a more polar or faster-dissolving plasticizer.
Plasticizer with low solvent power may require higher temperature or longer time.
The main characteristics of LACOVYL PVC PB1302 at the molecular and morphological level are:
Structure of vinyl chloride homopolymer
Chlorine-containing polar carbon chain
Molecular weight class about K70
Microsuspension particle morphology
Fine particle structure
Ability to form plastizole in plasticizer
Ability to show gelation by heating
Continuous PVC matrix formation after fusion
Low plastisol viscosity
High brightness potential
Suitability for low-plasticizer formulations

Note: These plastizole viscosity values depend on the specified PVC/plasticizer composition and aging conditions.
These reference values are not the "viscosity" of pure PB1302 powder.
It is the formulation viscosity that is measured after the plastisol resin is dispersed in the plasticizer.
This distinction is important in technical comparisons.
The same grade PB1302 can show markedly different viscosity at DINP, DINCH, DOTP, or other plasticizer levels.
Adding filler can also increase viscosity.
Therefore, TDS viscosity should be used as a quality control reference and the final formulation viscosity should be measured separately.
HOW DOES LACOVYL PVC PB1302 WORK AT THE MOLECULAR LEVEL?
The basic working mechanism of LACOVYL PVC PB1302 is the dispersion of plastic particles within the plasticizer and their transformation into the continuous PVC phase through gelation-fusion when temperature is applied.
In the mixing stage, the PVC particles are dispersed in the liquid plasticizer.
At this stage, the system is called plastizole.
The viscosity of plastisol depends on the resin particle structure, the amount of plasticizer, and the filler/pigments used.
The low viscosity character of PB1302 can provide a significant advantage in systems with high solids.
When heating begins, the plasticizer disperses the molecules into the amorphous regions of the PVC particles. The particles swell. The viscosity increases. This stage is defined as gelation.
As the temperature rises further, the boundaries between PVC particles begin to disappear.
The chains and the plasticizer form a more homogeneous phase. This stage is defined as fusion.
After cooling, the plasticizer remains between the PVC chains.
The material can show flexible, semi-rigid or compact structure according to the target amount of plasticizer.
At a low plasticizer level, harder and mechanically stronger compact PVC can be obtained.
A softer and more flexible product is produced at a high plasticizer level.
The K70 level of PB1302 can contribute to maintaining adequate film integrity in low-plasticizer formulations. The fine particle structure promotes the smoothness of the surface.
Therefore, it can be preferred for glossy coatings and thin top coat applications.
Pseudoplastic flow can help plasticzole diffuse more easily under high shear.
Rising viscosity after coating is completed can reduce the risk of runoff or sagging.
The primary functions of LACOVYL PVC PB1302 at the formulation and process level are:
Plastisol to form the main PVC resin
Making a cake with plasticizer
Develop low viscosity formulation
Facilitating the application of the thin coating
Supporting the use of high filler
Enabling low-plasticizer systems
PVC film formation after gelation and fusion
Providing high surface gloss
Compact PVC sheet development
Providing resin matrix suitable for dip and rotational molding processes

The main uses of LACOVYL PVC PB1302 are compact and low viscosity plastisol applications.
The current KEM ONE product registration also clearly shows rotation molding and dipping between applications.
FLOOR, WALL CLADDING AND COATED FABRIC APPLICATIONS OF LACOVYL PVC PB1302
Floor and wall coverings are among the primary commercial applications of LACOVYL PVC PB1302.
PVC flooring can consist of multi-layer systems.
Saturation layer
Support layer
Foam layer
Printing layer
Wear layer
Upper floor
There can be various layers, for example.
PB1302 can be used in saturation and compact layer applications, especially those requiring low viscosity.
The fine particle structure contributes to the uniform finish.
Its high glossy nature can be advantageous on decorative surfaces.
In the floor covering, it may be desired to drill the plastizol fabric, felt or other rear sole surface.
Too high viscosity can limit this penetration.
The liquefied plastisol character of PB1302 can be advantageous for the saturation process.
It can be used in wall coverings, top floor and foundation floor systems.
Surface smoothness, gloss and flawless finish are important in top coat application.
In basal coat application, coverage, adhesion and formulation costs may come to the fore.
In high-filler formulations, PB1302's low base viscosity can be significant.
As fillers like calcium carbonate are added, plastisol viscosity increases.
Low viscosity starting resin can provide process window for higher filler loading.
In coated fabric applications, PVC plastisol is applied to the fabric and then thermal gelation/fusion is performed.
When a low plasticizer system is required, the compact quality character of PB1302 is an advantage.
Fogging is also important in automotive coated fabric applications.
When vehicle interior materials release volatile or semi-volatile components at high temperatures, films can form on windows.
KEM ONE sources demonstrate the low fogging of the PB1302 as an advantage in such applications.
However, the final fogging performance is strongly influenced by the choice of plasticizer.
USE OF LACOVYL PVC PB1302 IN DIPPING, DECENTRALIZING, COIL COATING, AND ROTOMOLDING APPLICATIONS
LACOVYL PVC PB1302 can be used in dipping applications.
In the dipping process, a mold or part is immersed in plastizole.
Putty of a certain thickness adheres to the surface.
Subsequently, gelation and fusion are carried out by controlled heating.
Plastisol viscosity directly affects coating thickness.
The low viscosity character of PB1302 can be beneficial in thin and uniform dipping layers.
If higher film thickness is desired, the viscosity of the formulation or dip cycle should be modified.
In sealing and sealant applications, PVC paste elastic can be the main resin of plastisol systems containing fillers.
In these systems, the high filling capacity of PB1302 is economically and rheologically important.
In coil coating applications, the coating is applied to the continuous metal surface.
Controlled flow and even film are required at high line speed.
Low viscosity paste PVC can be advantageous in this process.
In rotomolding, plastisol is taken into the mold.
As the mold moves multiaxially, temperature is applied.
Put PVC gel on the inner surface of the mold and combine it.
When the mold is cooled, a hollow, flexible or semi-rigid PVC part can be obtained.
Toys and some automotive parts can be produced with this technique.
For rotational molding, the plastisol's low viscosityity, homogeneous spreading, and good deaeration behavior are important.
PB1302 is explicitly recommended in current commercial sources for this application.
IS LACOVYL PVC PB1302 USED IN KIDA, COSMETIC, AND PHARMACEUTICAL APPLICATIONS?
LACOVYL PVC PB1302 is a technical plastisol PVC resin.
It is not a direct food additive.
This is not a cosmetic formulation raw material.
It is not a pharmaceutical active or excipient.
PVC can be used in some food contact, medical device, or pharmaceutical packaging applications.
However, just because a particular PVC resin is CAS 9002-86-2 does not mean it is suitable for these uses.
All plasticizers, stabilizers, pigments, lubricants and other additives in the final compound must comply with the target legislation.
The suitability of LACOVYL PB1302 for specific food contact, medical, or pharmaceutical applications should not be assumed without available regulatory documentation from the manufacturer.
Especially in plastizole PVC systems, the choice of plasticizer is critical in terms of migration and removable/leachable substances.
INDUSTRIAL APPLICATIONS OF LACKOVIL PVC PB1302
LACOVYL PVC PB1302 is used as the main PVC binder/resin phase in industry.
The following functions may be prominent in industrial LACOVYL PVC PB1302 applications:
Production of plastizol
Compact PVC coating production
Floor covering production
Production of wall cladding
Coated fabric production
Automotive coated fabric production
Low plasticizer PVC formulation
High-fill plastisol formulation
Immersion compound production
Rotomolding compound production
Sealing production
Mastic production
Coil coating
Adhesion layer production
Mechanical foam coating
High glossy PVC surface production
Thin coating layer production
Low fog automotive PVC systems
In the formulation of LACOVYL PVC PB1302, a 100 phr PVC base is generally accepted.
The plasticizer, filler, and other components can be calculated as pH based on this resin.
For example, 50 phr plasticizer means 50 weight units of plasticizer per 100kg of PVC resin unit.
The plasticizing range of 30–70 phr specified for PB1302 should be interpreted in this context.
This value is the recommended formulation window of the product.
Depending on the application, the actual formulation may be different.
At a low level of plasticizer, plastizole viscosity and process conditions should be carefully controlled.
When high fillers are used, dispersion quality becomes critical.
Filler surface treatment and particle size can have a significant impact on rheology.
The stabilizer system is essential to limit the thermal degradation of PVC during fusion.
PVC can undergo a high-temperature dehydrochlorination reaction.
Therefore, Ca/Zn, organotin or other heat stabilizer systems that comply with the target legislation can be used.
The choice should be based on the final implementation.
The following issues should be considered in the use of LACOVYL PVC PB1302 in industrial systems:

WHAT PROBLEMS CAN LACOVYL PVC PB1302 SOLVE?
LACOVYL PVC PB1302 can help solve technical problems, especially in plastizole viscosity, high filler, low plasticizer usage and obtaining a glossy finish.
Plastisol viscosity is too high
PB1302 can help develop low viscosity plastisol as a multi-liquid paste resin.
Loss of machinability at high fill level
Low initial viscosity can contribute to the formulation remaining within the usable rheology range after filler is added.
Difficulty in preparing plastisols in low plasticizer system
PB1302 is specifically positioned for low-plasticized systems within plasticization windows of approximately 30–70 phr.
Low gloss on coating
Fine particle structure and K70 molecular profile can promote more uniform and bright PVC surface.
Surface defects in thin coating
Its fine particle structure can help in the production of very thin and flawless layers.
Coating does not spread sufficiently at high speed
Fluid rheology under shear can be advantageous in high-speed plating processes.
High fogging in the coated fabric system
PB1302 is positioned as a low mist resin; however, low volatility plasticizer and suitable additives should also be selected for final performance.
Poor propagation of plastisol in the mold in rotomolding
Low viscosity, flat wetting and can improve mold surface finish.
Plastisol exhibits excessive viscosity increase during storage
This issue is not just related to PVC resin.
The plasticizer solvent, filler, dispersant, water pollution and aging should be examined together.
Thermal yellowing of PVC film
PB1302 alone cannot solve this problem.
The heat stabilizer system, fusion temperature, and lead time should be optimized.
Not every plastisol problem can be solved by simply moving to the PB1302 level.
It should be considered as resin, plasticizer, additive and process whole.
THINGS TO CONSIDER WHEN USING LACOVYL PVC PB1302
Plastizole rheology, thermal treatment, and formulation compatibility are the major technical issues in the use of LACOVYL PVC PB1302.

ALTERNATIVES AND COMPARISON OF LACKOVIL PVC PB1302
When choosing a LACOVYL PVC PB1302 alternative, the definition of "PVC paste resin" should not be looked at in isolation.
K-value, plastizole viscosity, particle morphology, plasticizer demand, and target application should be evaluated together.
LACOVYL PVC PB1302 AND LACOVYL PB1202
LACOVYL PB1202 is one of the lower K-valued grades in the same PVC paste product family.
In the former KEM ONE technical portfolio, PB1202 is listed as approximately K67.
The PB1202 is positioned with a very streamlined character, especially for high fill loading.
PB1302 is a K70 level multi-purpose and bright-focused grade.
Both products can be considered in the application of high-fill plastisol, but the film mechanical properties and gloss behavior may differ.
LACOVYL PVC PB1302 AND LACOVYL PB1172H
PB1172H is another very fluid PVC putty grade with a lower K-value.
It is positioned in the legacy product portfolio for low-plasticized applications and molding.
With its higher K70 rating, the PB1302 may offer a different balance of mechanical performance and brightness.
Plastisol rheology and film properties should be tested without direct one-to-one replacement.
LACOVYL PVC PB1302 AND LACOVYL PB1405
PB1405 is higher molecular weight PVC grade with about K75.
In older KEM ONE welds, it is positioned specifically for textile adhesion.
PB1302 is suitable for multi-purpose compact applications with plastisol viscosity of about K70 and lower.
PB1405 can provide higher adhesion or mechanical performance, but the viscosity profile may differ.
LACOVYL PVC PB1302 AND LACOVYL PB1702
PB1702 is higher K-value PVC putty grade at about K80 level.
Higher molecular weight can improve the final mechanical properties.
However, plastizol rheology and gelation behavior vary.
PB1702 has been associated with mechanical properties and a semi-matte appearance in older product tables.
PB1302 is more advantageous in terms of brightness and easy fluid behavior.
LACOVYL PVC PB1302 AND GENERAL SUSPENSION PVC
Suspension PVC and adhesive PVC can have the same polyvinyl chloride chemistry.
However, the particle size and morphology are completely different.
Suspension PVC is in the form of granules with large pores and is used in processes such as dry mix extrusion or calendering.
PB1302 consists of very fine pulp resin particles and is designed to prepare plastizole.
General suspension PVC is not a direct replacement for PB1302 in plastisol application.

The K-value is the critical parameter for verifying the molecular weight class of the product.
The viscosity number supports the same information with a different analytical approach.
Bulk density is important for logistics and mixing behavior.
Moisture can have an impact on plastizol, rheology, and surface finish.
High water levels can cause foam, pinhole, or viscosity instability in some plastisol systems.
Elep is important for residue and particle fine coating surface.
Coarse, agglomerates can cause surface defects in the thin coating.
The reference plastisol viscosity is an important criterion for supplier change evaluation.
If the same K70 paste PVC has different particle morphology, the viscosity of plastizole can vary greatly.
Therefore, the alternative grade should not be chosen based solely on its K-value.
STORAGE AND PROCESSING OF LACKOVIL PVC PB1302
Storage: LACOVYL PVC PB1302 should be stored in a dry, clean storage area protected from heat sources.
Moisture Agent: The packaging should be kept sealed to prevent unnecessary moisture ingress.
PVC paste resin moisture can have adverse effects on formulation, rheology, and thermal treatment.
Heat: The product should be kept away from direct or indirect heat sources.
The old KEM ONE white paper states that resin should be stored in a dry environment away from all direct and indirect heat sources.
Shelf life: The old KEM ONE PB1302 white paper states a shelf life of approximately 18 months under recommended storage conditions.
This period must be confirmed from the manufacturer before placing an order for the current commercial product.
Packaging: The old technical document contains information about a 25 kg bag and a pallet wrapped in polyethylene.
The current packaging format must be verified by the supplier.
Dust control: Dust spread should be limited as much as possible during bag emptying.
Transfer: Resin agglomeration and contamination should be controlled in pneumatic or mechanical conveyor systems.
FIFO: Managing batch age is particularly beneficial for plastisol rheology consistency.
Transport: The current transport and safety classification must be fully verified from KEM ONE SDS.
LACOVYL PVC PB1302 SAFETY INFORMATION
LACOVYL PVC PB1302 is solid PVC polymer powder.
Its volatility is very low at normal ambient temperature.
Basic workplace exposure can occur through dust generation.
Proper local ventilation should be implemented during bag emptying, silo transfer, and high-speed mixing.
Intense exposure to the eyes and respiratory area should be avoided.
Safety during PVC resin processing should not be solely evaluated on the raw resin.
Plasticizers, stabilizers, pigments, blowing agents, and other additives have their own SDS requirements.
If PVC undergoes thermal degradation at high processing temperature, hydrogen chloride and other decay products may form.
Therefore, extreme temperature and residence time should be avoided during thermal treatment.
Appropriate heat stabilizer should be used.
Safe use, fire, spill, dust control and personal protective equipment must be based on the exact existing SDS document.
WHAT TO CONSIDER WHEN BUYING LACOVYL PVC PB1302?

The price of LACOVYL PVC PB1302 should not be evaluated solely based on the resin cost per ton.
Low viscosity allows for higher filler or lower plasticizer usage, which can impact the overall cost of the formulation.
Coating speed, scrap rate, surface finish, and gloss should also be factored into the economic consideration.
Even if the alternative putty PVC grade has the same K70 value, the rheology may not be the same.
Therefore, it is important to conduct pilot plastisol testing.

LACOVYL PVC PB1302 – TECHNICAL SUMMARY
LACOVYL PVC PB1302 is a grade of polyvinyl chloride homopolymer resin produced by the microsuspension method offered by KEM ONE for plastisol applications.
The product is identified by CAS No 9002-86-2 for its overall PVC identity. Since PVC is a polymer, it is characterized by its K-value and viscosity number rather than a single molecular weight.
LACOVYL PVC PB1302 has a K-value of approximately 70 and a viscosity count of approximately 125 mL/g according to ISO 1628-2.
In the old KEM ONE technical data, the bulk density is given as approx. 0.40 g/cm³, the moisture < 0.25%, the water extract pH approx. 7, and the sieve residue < 63 μm as 1%.
The product has a very fine particle structure and enables the preparation of low viscosity plastisol. Commercial sources describe the rheology profile from high fluid pseudoplastic to quasi-Newtonian behavior.
It can be used in a plasticizing range of about 30–70 phr and is particularly suitable for high-fill formulations with low or very low levels of plasticizers.
LACOVYL PVC PB1302 can be used in flooring, saturation/backlayer, wall covering/base coating, coating fabrics, adhesion layers, sealants, dipping, coil coating and rotomolding applications.
Fine particle structure supports fine flawless coating and high gloss.
Low fogging can be advantageous in automotive coated fabric applications, but the final fogging performance should be tested in conjunction with the plasticizer and other compounding components.
When LACOVYL PVC PB1302 forms plastisol, the PVC particles are dispersed in the plasticizer. In the thermal process, the particles first swell and turn into gels, then a continuous plasticized PVC matrix is formed as a result of fusion.
The product is not a final compound. The heat stabilizer, plasticizer, filler, pigment, and other additives specific to the target application must be formulated separately.
When selecting the LACOVYL PVC PB1302 alternative, the K70 value alone should not be considered. Particle morphology, reference plastisol viscosity, filler acceptance, and gloss behavior should be compared.
Companies planning to purchase LACOVYL PVC PB1302 from Ataman Kimya are advised to verify the current product and present the conditions by sharing the final application, plasticizer type and level, filler filler loading, target rheology, polishing/fogging requirement, packaging quantity, and technical documentation needs.
