LACOVYL PVC PB1302 is a polyvinyl chloride–based paste resin designed for plastisol and coating applications where controlled viscosity, good film formation, and mechanical stability are required.
Chemically, it is a high-molecular-weight vinyl polymer produced by emulsion or micro-suspension polymerization, giving fine particle size and high surface area for efficient plasticizer absorption.
The polymer backbone consists of repeating –CH₂–CHCl– units, which provide rigidity, chemical resistance, and good compatibility with common plasticizers and stabilizers.
In formulation chemistry, LACOVYL PVC PB1302 readily swells in plasticizers to form stable plastisols with adjustable rheology and gelation behavior.
Upon heating, the PVC particles dissolve into the plasticizer phase and fuse into a continuous thermoplastic film with good adhesion and flexibility.
The material exhibits good resistance to water, dilute acids, alkalis, oils, and many solvents, making it suitable for demanding industrial coatings and flexible products.
From a materials perspective, this grade offers balanced particle distribution, low volatile content, and consistent fusion temperature, which supports reproducible processing in coating, dipping, spreading, and molding operations.
The polymer structure provides good mechanical strength, abrasion resistance, and dimensional stability after curing.
LACOVYL PVC PB1302 is compatible with pigments, fillers, stabilizers, and functional additives used in PVC compounding systems.
Proper storage in dry, cool conditions is required to avoid moisture uptake and agglomeration.
Pure polyvinyl chloride is a white, brittle solid.
LACOVYL PVC PB1302 exhibits good thermal stability up to 150°C and is much more oil resistant than nonpolar elastomers such as natural rubber or EPDFM.
Commercial products are soft when the chlorine content is 28–38%.
At more than 45% chlorine content, the material resembles polyvinyl chloride.
Higher-molecular-weight polyethylene yields a chlorinated polyethylene that has both high viscosity and tensile strength.
In chlorinating polyethylene, chlorine atoms substitute for hydrogen atoms of the polyethylene chain in both crystalline and amorphous regions.
The most common chlorination method is treating polyethylene powder in an aqueous suspension that contains hydrochloric acid and a free-radical initiator with chlorine gas.
After the desired level of chlorination is obtained, the CPE is water washed and dried, and an antiblocking agent is then added.
The manufacture of polyvinyl chloride resins commences with the monomer, vinyl chloride, which is a gas, shipped and stored under pressure to keep it in a liquid state; bp ?14 °C, fp ?160 °C, density (20 °C), 0.91.
The monomer is produced by the reaction of hydrochloric acid with acetylene.
This reaction can be carried out in either a liquid or gaseous state.
In another technique, ethylene is reacted with chlorine to produce ethylene dichloride.
This is then catalytically dehydrohalogenated to produce vinyl chloride the by-product is hydrogen chloride.
A later process, oxychlorination, permits the regeneration of chlorine from HCl for recycle to the process.

LACOVYL PVC PB1302 is an industrial-grade polyvinyl chloride paste resin engineered specifically for plastisol processing, surface coating, and flexible PVC product manufacturing.
It consists of long-chain vinyl chloride repeat units that create a chemically inert thermoplastic polymer with high mechanical integrity and excellent durability.
The resin is manufactured using controlled emulsion or microsuspension polymerization, producing uniform fine particles that enable fast plasticizer absorption and predictable gelation behavior.
From a polymer chemistry standpoint, the chlorine atoms along the polymer backbone increase polarity, chemical resistance, and flame-retardant characteristics compared to non-halogenated polymers.
The polymer chains exhibit strong intermolecular interactions that provide dimensional stability and resistance to deformation after fusion.
Molecular weight distribution is optimized to balance viscosity control, film strength, and processing window in plastisol systems.
In dispersion systems, LACOVYL PVC PB1302 forms stable plastisols with adjustable rheology depending on plasticizer type, filler loading, and shear conditions.
During heating, the PVC particles swell, dissolve into the plasticizer phase, and coalesce into a homogeneous continuous film without chemical crosslinking.
This thermal fusion process yields smooth surfaces, good adhesion to substrates, and consistent mechanical performance.
The resin demonstrates good resistance to water, dilute acids, dilute alkalis, oils, greases, and many industrial chemicals, making it suitable for demanding environments.
LACOVYL PVC PB1302 exhibits low water absorption and good electrical insulation properties, which are beneficial for technical coatings and protective layers.

These fumes are corrosive and irritating to the eyes, skin, and respiratory system and must be controlled by adequate ventilation and exhaust systems.
Overheating or burning of the material significantly increases toxic fume generation.
