Hydrocarbon Resins (Escorez)
The Inventive Resin was also compared with some 5 competitive resin samples. Tested were Escorez 1310 LC, an aliphatic resin like Piccotac 95E, and Escorez 2203 LC, a slightly aromatic modified resin comparable to Hercotac 1148.
Further Hercules RESIN A was compared as well.
10 Hercules RESIN A is like Hercules RESIN B a more aromatic modified resin than Escorez 2203 LC and Hercotac 1148. Shear to steel 120 73 134 177 20 (40 C,2.5 kg,min) Shear to steel 809 1446 781 102 (70 C,0.5 kg,min) The results clearly show again that the melt viscosity and the rolling ball tack using the Inventive 25 Resin are comparable to a slightly aromatic modified resin like Escorez 2203 LC. The rolling ball tack using Hercules RESIN A was found to be higher due to the higher molecular weight. The hot melt viscosity using Escorez 1310 LC is higher than observed for Piccotac 95E
and especially the Inventive Resin. The shear to steel at 70 C using the Inventive Resin was found to be better than for the Hercules RESIN A. The use of Escorez 2203 LC gives a better high temperature shear to steel like 5 found for Piccotac 95E but also gives the highest viscosity .Escorez 1310 LC - A petroleum resin available from Exxon containing about 0.3% by weight of polymerized 5 styrene and having a softening point of about 93.5 C.

Naphtha (Escorez 2203 LC) (/ˈnæpθə/ or /ˈnæfθə/) is a flammable liquid hydrocarbon mixture.
Mixtures labelled Naphtha (Escorez 2203 LC) have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat.
In different industries and regions Naphtha (Escorez 2203 LC) may also be crude oil or refined products such as kerosene. Mineral spirits, also historically known as "Naphtha (Escorez 2203 LC)", is not the same chemical.[citation needed]
Nephi and Naphtha (Escorez 2203 LC)r are sometimes used as a synonyms.[1]. It is also known as Shellite in Australia[2].

Etymology of Escorez 2203 LC
White gas, exemplified by Coleman Camp Fuel, is a common Naphtha (Escorez 2203 LC)-based fuel used in many lanterns and torches
The word Naphtha (Escorez 2203 LC) is from Latin and Ancient Greek (νάφθα), derived from Middle Persian naft ("wet", "Naphtha (Escorez 2203 LC)"),[3][4] the latter meaning of which was an assimilation from the Akkadian napṭu (see Semitic relatives such as Arabic نَفْط nafṭ ["petroleum"], Syriac ܢܰܦܬܳܐ naftā) and Hebrew נֵפְט neft (meaning petroleum).[5] In Ancient Greek, it was used to refer to any sort of petroleum or pitch.
In the Song of the Three Children the Greek word νάφθα designates one of the materials used to stoke the fiery furnace. The translation of Charles Brenton renders this as "rosin".
The book of II Maccabees tells how a "thick water" was put on a sacrifice at the time of Nehemiah and when the sun shone it caught fire. It adds that "those around Nehemiah termed this 'Nephthar', which means Purification, but it is called Nephthaei by the many [literally hoi polloi]."[6]
It enters the word napalm, a contraction of the "na" of naphthenic acid and "palm" of palmitic acid, originally made from a mixture of naphthenic acid combined with aluminium and magnesium salts of palmitic acid. Naphtha (Escorez 2203 LC) is the root of the word Naphtha (Escorez 2203 LC)lene, and can also be recognised in the word phthalate, and the paint colour phthalo blue.
In older usage, "Naphtha (Escorez 2203 LC)" simply meant crude oil, but this usage is now obsolete in English. It was also used for mineral spirits (also known as "Stoddard Solvent"), originally the main active ingredient in Fels Naptha laundry soap. The Ukrainian and Belarusian word нафта (nafta), Lithuanian, Latvian and Estonian "nafta" and the Persian naft (نفت) mean "crude oil". The Russian word нефть (neft') means "crude oil", but нафта (nafta) is a synonym of ligroin. Also, in Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Finland, Italy, Serbia, Slovenia, Macedonia nafta (нафта in Cyrillic) is colloquially used to indicate diesel fuel and crude oil. In the Czech Republic and Slovakia, nafta was historically used for both diesel fuel and crude oil, but its use for crude oil is now obsolete[7] and it generally indicates diesel fuel. In Bulgarian, nafta means diesel fuel, while neft, as well as petrol (петрол in Cyrillic), means crude oil. Nafta is also used in everyday parlance in Argentina, Paraguay and Uruguay to refer to gasoline/petrol.[8] In Poland, the word nafta means kerosene,[9] and colloquially crude oil (technical name for crude oil is ropa naftowa, also colloquially used for diesel fuel as ropa). In Flemish, the word naft is used colloquially for gasoline.[10]
There is a hypothesis that the word is connected with the name of the Indo-Iranian god Apam Napat, which occurs in Vedic and in Avestic; the name means "grandson of (the) waters", and the Vedas describe him as emerging from water golden and shining "with bright rays", perhaps inspired by a burning seepage of natural gas.[11]
Types of Escorez 2203 LC
Various qualifiers have been added to the term "Naphtha (Escorez 2203 LC)" by different sources in an effort to make it more specific:
One source[12] distinguishes by boiling point:
Light Naphtha (Escorez 2203 LC) is the fraction boiling between 30 °C and 90 °C and consists of molecules with 5-6 carbon atoms. Heavy Naphtha (Escorez 2203 LC) boils between 90 °C and 200 °C and consists of molecules with 6-12 carbon atoms.
Another source[13] differentiates light and heavy comments on the hydrocarbon structure, but offers a less precise dividing line:
Light [is] a mixture consisting mainly of straight-chained and cyclic aliphatic hydrocarbons having from five to six carbon atoms per molecule. Heavy [is] a mixture consisting mainly of straight-chained and cyclic aliphatic hydrocarbons having from seven to nine carbon atoms per molecule.
Both of these are useful definitions, but they are incompatible with one another and the latter does not provide for mixes containing both six and seven carbon atoms per molecule. These terms are also sufficiently broad that they are not widely useful.
Uses of Escorez 2203 LC
Heavy crude oil dilution
Naphtha (Escorez 2203 LC) is used to dilute heavy crude oil to reduce its viscosity and enable/facilitate transport; undiluted heavy crude cannot normally be transported by pipeline, and may also be difficult to pump onto oil tankers. Other common dilutants include natural-gas condensate, and light crude. However, Naphtha (Escorez 2203 LC) is a particularly efficient dilutant and can be recycled from diluted heavy crude after transport and processing.[14][15][16] The importance of oil dilutants has increased as global production of lighter crude oils has fallen and shifted to exploitation of heavier reserves.[15]
Fuel of Escorez 2203 LC
Light Naphtha (Escorez 2203 LC) is used as a fuel in some commercial applications. One notable example is the Zippo lighter, which draws Naphtha (Escorez 2203 LC) into a wick from a reservoir to be ignited using the flint and wheel.
It is also a fuel for camping stoves and oil lanterns, Naphtha (Escorez 2203 LC)'s low boiling point making it easy to ignite. Naphtha (Escorez 2203 LC) is sometimes preferred over kerosene due to a lower incidence of fuel line clogging.
Plastics of Escorez 2203 LC
Naphtha (Escorez 2203 LC) is a crucial component in the production of plastics.[17]
Health and safety considerations
The safety data sheets (SDSs) from various Naphtha (Escorez 2203 LC) vendors are also indicative of the non-specific nature of the product and reflect the considerations due for a flammable mixture of hydrocarbons: flammability, carcinogenicity, skin and airway irritation, etc.[18][2][19][20]
Humans can be exposed to Naphtha (Escorez 2203 LC) in the workplace by inhalation, ingestion, dermal contact, and eye contact. The US Occupational Safety and Health Administration (OSHA) has set the permissible exposure limit for Naphtha (Escorez 2203 LC) in the workplace as 100 ppm (400 mg/m3) over an 8-hour workday. The US National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 100 ppm (400 mg/m3) over an 8-hour workday. At levels of 1000 ppm, which equates to 10% of the lower explosive limit, Naphtha (Escorez 2203 LC) is immediately dangerous to life and health.
 

Petroleum naphtha (Escorez 2203 LC) is an intermediate hydrocarbon liquid stream derived from the refining of crude oil[1][2][3] with CAS-no 64742-48-9.[4] It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha (Escorez 2203 LC) as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or petrol).
There are hundreds of different petroleum crude oil sources worldwide and each crude oil has its own unique composition or assay. There are also hundreds of petroleum refineries worldwide and each of them is designed to process either a specific crude oil or specific types of crude oils. naphtha (Escorez 2203 LC) is a general term as each refinery produces its own naphtha (Escorez 2203 LC)s with their own unique initial and final boiling points and other physical and compositional characteristics.
naphtha (Escorez 2203 LC)s may also be produced from other material such as coal tar, shale deposits, tar sands, and the destructive distillation of wood.
The major source of petroleum naphtha (Escorez 2203 LC) in a petroleum refinery
The first unit operation in a petroleum refinery is the crude oil distillation unit. The overhead liquid distillate from that unit is called virgin or straight-run naphtha (Escorez 2203 LC) and that distillate is the largest source of naphtha (Escorez 2203 LC) in most petroleum refineries. The naphtha (Escorez 2203 LC) is a mixture of many different hydrocarbon compounds. It has an initial boiling point (IBP) of about 35 °C and a final boiling point (FBP) of about 200 °C, and it contains paraffins, naphthenes (cyclic paraffins) and aromatic hydrocarbons ranging from those containing 4 carbon atoms to those containing about 10 or 11 carbon atoms.
The virgin naphtha (Escorez 2203 LC) is often further distilled into two streams:[7]
a virgin light naphtha (Escorez 2203 LC) with an IBP of about 30 °C and a FBP of about 145 °C containing most (but not all) of the hydrocarbons with six or fewer carbon atoms
a virgin heavy naphtha (Escorez 2203 LC) containing most (but not all) of the hydrocarbons with more than six carbon atoms. The heavy naphtha (Escorez 2203 LC) has an IBP of about 140 °C and a FBP of about 205 °C.
The virgin heavy naphtha (Escorez 2203 LC) is usually processed in a catalytic reformer, because the light naphtha (Escorez 2203 LC) has molecules with six or fewer carbon atoms-which, when reformed, tend to crack into butane and lower molecular weight hydrocarbons that are not useful as high-octane gasoline blending components. Also, the molecules with six carbon atoms tend to form aromatics, which is undesirable because the environmental regulations of a number of countries limit the amount of aromatics (most particularly benzene) in gasoline.[8][9][10]
Types of virgin naphtha (Escorez 2203 LC)s
The table below lists some typical virgin heavy naphtha (Escorez 2203 LC)s, available for catalytic reforming, derived from various crude oils. It can be seen that they differ significantly in their content of paraffins, naphthenes and aromatics:
Some refinery naphtha (Escorez 2203 LC)s also contain some olefinic hydrocarbons, such as naphtha (Escorez 2203 LC)s derived from the fluid catalytic cracking, visbreakers and coking processes used in many refineries. Those olefin-containing naphtha (Escorez 2203 LC)s are often referred to as cracked naphtha (Escorez 2203 LC)s.
In some (but not all) petroleum refineries, the cracked naphtha (Escorez 2203 LC)s are desulfurized and catalytically reformed (as are the virgin naphtha (Escorez 2203 LC)s) to produce additional high-octane gasoline components.
Some petroleum refineries also produce small amounts of specialty naphtha (Escorez 2203 LC)s for use as solvents, cleaning fluids and dry-cleaning agents, paint and varnish diluents, asphalt diluents, rubber industry solvents, recycling products, and cigarette-lighter, portable-camping-stove and lantern fuels. Those specialty naphtha (Escorez 2203 LC)s are subjected to various purification processes which adjusts chemical characteristics to suit specific needs.
Specialty naphtha (Escorez 2203 LC) comes in many varieties and each are referred to by separate names such as petroleum ether, petroleum spirits, mineral spirits, paraffin, benzine, hexane, ligroin, white oil or white gas, painters naphtha (Escorez 2203 LC), refined solvent naphtha (Escorez 2203 LC) and Varnish makers' & painters' naphtha (Escorez 2203 LC) (VM&P). The best way to determine the boiling point and other compositional characteristics of any of the specialty naphtha (Escorez 2203 LC) is to read the Safety Data Sheet (SDS) for the specific naphtha (Escorez 2203 LC) of interest. Safety Data Sheets can be found on a chemical suppliers websites or by contacting the supplier directly.
On a much larger scale, petroleum naphtha (Escorez 2203 LC) is also used in the petrochemicals industry as feedstock to steam reformers and steam crackers for the production of hydrogen (which may be and is converted into ammonia for fertilizers), ethylene, and other olefins. Natural gas is also used as feedstock to steam reformers and steam crackers.
Safety
People can be exposed to petroleum naphtha (Escorez 2203 LC) in the workplace by breathing it, swallowing it, skin contact, and eye contact. The Occupational Safety and Health Administration (OSHA) set the legal limit (permissible exposure limit) for petroleum naphtha (Escorez 2203 LC) exposure in the workplace as 500 ppm (2000 mg/m3) over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a recommended exposure limit (REL) of 350 mg/m3 over an 8-hour workday and 1800 mg/m3 over 15 minutes. At levels of 1100 ppm, 10% of the lower explosive limit, petroleum naphtha (Escorez 2203 LC) is immediately dangerous to life and health.
 

Naphtha (Escorez 2203 LC) feed containing complex sulphur compounds and dissolved oxygen, is fed to a stripper column, where dissolved oxygen is removed using off-gas, as higher oxygen content in Naphtha (Escorez 2203 LC) will lead to heavy fouling in the downstream exchanger train. The stripper overhead is connected to the fuel gas system, the excess gas being flared off. The deaerated Naphtha (Escorez 2203 LC) is pumped to an exchanger train where it is heated from reactor effluent stream and then fed to a fired heater. Here Naphtha (Escorez 2203 LC) is vaporized, which along with hydrogen rich feed gas is send to the desulphurization reactor.
The reactor effluent exchanges heat with feed Naphtha (Escorez 2203 LC) in the P-Heater exchanger train, and is then further cooled in an air cooler. The treated Naphtha (Escorez 2203 LC) is send to the next section of the utility plant for further processing.
Naphtha (Escorez 2203 LC) is an important resource used to produce petrochemical products. Historically, petrochemical companies have been keen to the variations of Naphtha (Escorez 2203 LC) prices as it has had great effects on their profits. Naphtha (Escorez 2203 LC) price is closely aligned with crude oil price. In particular, more directly, supply and demand of Naphtha (Escorez 2203 LC) affect its price fluctuations. This research is focused to propose an approach for forecasting supply and demand of Naphtha (Escorez 2203 LC), with an emphasis on key affecting factors such as the margin of petrochemical companies and the use of alternative raw material. The demand of Naphtha (Escorez 2203 LC) is estimated on the basis of the margin and operation rate of a petrochemical plant, while its supply is affected by operation rate of refinery. Modeling of forecasting Naphtha (Escorez 2203 LC) supply/demand, based on time series method, is developed along with absolute errors derived from a statistical analysis; the model at present time is used to forecast future supply/demand over historical time series data from March 2010 to September 2012. Key set of affecting factors are identified by combined heuristic and statistical analysis and a set of equations correlating between those factors are set up. The proposed model was validated by actual data for the underlying period, which should be useful to forecast the price of Naphtha (Escorez 2203 LC)
Naphtha (Escorez 2203 LC) and Gasoline
Naphtha (Escorez 2203 LC) processing proved to be challenging, due to its low octane numbers for FT Naphtha (Escorez 2203 LC). Brent et al.25 investigated FT Naphtha (Escorez 2203 LC) upgrading techniques. They approached two Naphtha (Escorez 2203 LC) reforming process providers, and were told by both that FT Naphtha (Escorez 2203 LC) was not a good reforming feedstock. Naphtha (Escorez 2203 LC) reforming increases octane numbers by increasing aromatic content, primarily through dehydrogenation of cycloalkanes. Instead, they chose to sell FT Naphtha (Escorez 2203 LC) as an olefin production feedstock. FT Naphtha (Escorez 2203 LC), compared to other Naphtha (Escorez 2203 LC)s, is an excellent olefin production feedstock because of its high alkane content. There are two problems with this approach. The first is that this would put FT Naphtha (Escorez 2203 LC) in direct competition with natural gas liquids, which sell at substantially lower prices than gasoline. The second is that olefin plants designed to use Naphtha (Escorez 2203 LC) feed are primarily located in countries that do not have significant natural gas production.
Naphtha (Escorez 2203 LC) is divided into two main types, aliphatic and aromatic. The two types differ in two ways: first, in the kind of hydrocarbons making up the solvent, and second, in the methods used for their manufacture. Aliphatic solvents are composed of paraffinic hydrocarbons and cycloparaffins (naphthenes), and may be obtained directly from crude petroleum by distillation. The second type of Naphtha (Escorez 2203 LC) contains aromatics, usually alkyl-substituted benzene, and is very rarely, if at all, obtained from petroleum as straight-run materials.
 

Generally, Naphtha (Escorez 2203 LC) is valuable as for solvents because of good dissolving power. The wide range of Naphtha (Escorez 2203 LC) available, from the ordinary paraffin straight-run to the highly aromatic types, and the varying degree of volatility possible offer products suitable for many uses (Boenheim and Pearson, 1973; Hadley and Turner, 1973).
The main uses of Naphtha (Escorez 2203 LC) fall into the general areas of (1) solvents (diluents) for paints, for example; (2) dry-cleaning solvents; (3) solvents for cutback asphalt; (4) solvents in the rubber industry; and (5) solvents for industrial extraction processes.
Turpentine, the older, more conventional, solvent for paints, has now been almost completely replaced with the discovery that the cheaper and more abundant petroleum Naphtha (Escorez 2203 LC) is equally satisfactory. The differences in application are slight: Naphtha (Escorez 2203 LC) causes a slightly greater decrease in viscosity when added to some paints than does turpentine, and depending on the boiling range, may also show difference in evaporation rate.
Naphtha (Escorez 2203 LC) is used in the rubber industry for dampening the play and tread stocks treating the treads of tires to obtain better road adhesion. They are also consumed extensively in making rubber cements (adhesives) or are employed in the fabrication of rubberized cloth, hot-water bottles, bathing caps, gloves, overshoes and toys. These cements are solutions of rubber and were formerly made with benzene, but petroleum Naphtha (Escorez 2203 LC) is now preferred because of its less toxic character.
Naphtha (Escorez 2203 LC) (often referred to as naft in the older literature) is a generic term applied to refined, partly refined, or an unrefined low-to-medium boiling petroleum distillate fraction. Naphtha (Escorez 2203 LC) resembles gasoline in terms of boiling range and carbon number, being a precursor to gasoline. In the strictest sense of the term, not less than 10% of the Naphtha (Escorez 2203 LC) should distill below 175°C (345°F) and not less than 95% of the material should distill below 240°C (465°F) under standardized distillation conditions (ASTM D86). The main uses of petroleum Naphtha (Escorez 2203 LC) fall into the general areas of (1) precursor to gasoline and other liquid fuels, (2) solvents (diluents) for paints, (3) dry-cleaning solvents, (4) solvents for cutback asphalts, (5) solvents in rubber industry, and (6) solvents for industrial extraction processes. Turpentine, the older and more conventional solvent for paints has now been almost completely replaced by the cheaper and more abundant petroleum Naphtha (Escorez 2203 LC).
The term petroleum solvent describes the liquid hydrocarbon fractions obtained from petroleum and is used in industrial processes and formulations. These fractions are also referred to as Naphtha (Escorez 2203 LC) or industrial Naphtha (Escorez 2203 LC). By definition, the solvents obtained from the petrochemical industry such as alcohols, ethers, and the like are not included in this chapter. A refinery is capable of producing hydrocarbons of a high degree of purity and at the present time petroleum solvents are available covering a wide range of solvent properties including both volatile and high boiling qualities. Other petroleum products boiling within the Naphtha (Escorez 2203 LC) boiling range include (1) industrial spirit and (2) white spirit.
Naphtha (Escorez 2203 LC) contains varying amounts of paraffins, olefins, naphthene constituents, and aromatics and olefins in different proportions, in addition to potential isomers of paraffin that exist in Naphtha (Escorez 2203 LC) boiling range. As a result, Naphtha (Escorez 2203 LC) is divided predominantly into two main types: (1) aliphatic Naphtha (Escorez 2203 LC) and (2) aromatic (Naphtha (Escorez 2203 LC)). The two types differ in two ways: first, in the kind of hydrocarbons making up the solvent, and second, in the methods used for their manufacture. Aliphatic solvents are composed of paraffinic hydrocarbons and cycloparaffins (naphthenes), and may be obtained directly from crude petroleum by distillation. The second type of Naphtha (Escorez 2203 LC) contains aromatics, usually alkyl-substituted benzene, and is very rarely, if at all, obtained from petroleum as straight-run materials.
Stoddard solvent is a petroleum distillate widely used as a dry cleaning solvent and as a general cleaner and degreaser. It may also be used as paint thinner, as a solvent in some types of photocopier toners, in some types of printing inks, and in some adhesives. Stoddard solvent is considered to be a form of mineral spirits, white spirits, and Naphtha (Escorez 2203 LC) but not all forms of mineral spirits, white spirits, and Naphtha (Escorez 2203 LC) are considered to be Stoddard solvent. Stoddard solvent consists of linear alkanes (30%-50%), branched alkanes (20%-40%), cycloalkanes (30%-40%), and aromatic hydrocarbons (10%-20%). The typical hydrocarbon chain ranges from C7 through C12 in length.
Turpentine, the older more conventional solvent for paints, has now been almost completely replaced with the discovery that the cheaper and more abundant petroleum Naphtha (Escorez 2203 LC) is equally satisfactory. The differences in application are slight: Naphtha (Escorez 2203 LC) causes a slightly greater decrease in viscosity when added to some paints than does turpentine, and depending on the boiling range, may also show difference in evaporation rate.
Reforming Shale Oil Naphtha (Escorez 2203 LC)
Shale oil Naphtha (Escorez 2203 LC)s produced during retorting or by thermal cracking have poor color and oxygen stability. They darken and form large amounts of gum soon after preparation. The instability of these shale oil Naphtha (Escorez 2203 LC)s and their high contents of nitrogen and sulfur make them poor feedstocks for modern noble-metal catalytic reforming processes. To overcome the problems of upgrading shale oil Naphtha (Escorez 2203 LC)s, production of stable Naphtha (Escorez 2203 LC)s by catalytic hydrogenation of crude shale oil or by coking crude shale oil, followed by hydrogenation of the coker distillate, is necessary. An investigation was carried out by Barker and Cottingham, 1976 [17-18] on catalytic reforming of hydrogenated Naphtha (Escorez 2203 LC) produced by hydrogenation of crude shale oil. A high quality reformate was obtained by refining a clean Naphtha (Escorez 2203 LC) at the highest temperature, 900° F, and the lowest pressure, 200 psig, that was used in the experimental work. Their product had a research octane number of 89, with the yield of reformate about 80 percent of the Naphtha (Escorez 2203 LC) charged.
 
Escorez™ Tackifying Resins are characterized as petroleum hydrocarbon tackifiers. There are two major
families. The first consist of major components that are C5-C6 olefins and diolefins (Escorez 1000 and 2000
series). These resins are catalytically polymerized. The second family consists of major components that
are Polycyclodienes (C10-C12 Cyclodiene dimers plus Dicyclopentadiene with or without C8-C10 vinyl
aromatics (Escorez 5000 series resins). These resins are thermally polymerized.

2. Product Uses
Escorez Tackifying Resins are used to enhance the tack properties of a variety of adhesive polymers. End
use applications may include Hot Melt Adhesives and Pressure Sensitive Adhesives.
3. Physical / Chemical Properties
Escorez Tackifying Resins are solid polymers that are stable and non-hazardous. If heated above the flash
point, they may burn or decompose to flammable hydrocarbons (fire situations). Safety hazards at ambient
temperature are generally negligible, due to their high molecular weight, minimal toxicity and general
inertness. These products do not possess the physical hazards of being a combustible liquid, a compressed
gas, explosive, flammable, an organic peroxide, an oxidizer, pyrophoric, unstable (reactive) or waterreactive. The flash point is estimated to be >392ºF /200ºC.
4. Health Information
Health hazards of Escorez Tackifying Resins, at ambient temperature are generally negligible. They are not
toxic, corrosive, sensitizers, reproductive toxins, or mutagenic, neurotoxic, or carcinogenic, and do not cause
specific target organ effects. No adverse health effects are expected with ingestion or inhalation. Prolonged
dermal or eye contact may result in slight irritation. Additives and potential impurities have been identified
and evaluated. The potential health hazards are negligible due to the low levels contained in the polymer and
the fact that the additives are encapsulated in the polymer. . Based on these evaluations, under U.S.
Occupational Safety and Health Administration (OSHA) rules, European Union regulations and the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (UN GHS) these products
are considered non-hazardous with regards to health effects.
5. Additional Hazard Information
When handling hot material, wear heat resistant gloves to protect your hands and skin. Immediately immerse
in or flush affected area with large amounts of cold water to dissipate heat. Cover with clean cotton sheeting
or gauze and get prompt medical attention. Health hazards may be associated with the additives or
impurities (e.g., unreacted monomers, solvent residues, reaction by-products). The identity and amount of
additives and impurities in ExxonMobil Chemical’s Resins have been evaluated. They are present at low
levels (i.e. much less than 1 wt. %). Additionally, the additives are encapsulated in the polymer. Therefore,
any potential hazards from additives and impurities are so greatly reduced that the polymers containing them
would not be classified as hazardous.
6. U.S. Food and Drug Administration (FDA) Regulated Uses
Appropriate manufacturing and distribution practices are employed to ensure the quality of this product when
offered for use in indirect additives to food contact applications.
7. Environmental Information
Escorez Tackifying Resins biodegrade at a slow rate and may persist in the environment. They are not
expected to cause short-term toxicity to fish or other aquatic organisms. Because of its low solubility in water,
chronic aquatic toxicity is not expected.
8. Exposure Potential
 Workplace exposure – This refers to potential exposure in a manufacturing facility or through
various industrial applications. Generally, exposure of personnel in manufacturing facilities is
relatively low due to the predominantly enclosed nature of the process, storage and handling
operations. Exposure can also occur from inhalation to particulate dusts in the packaging material.
The Occupational Safety and Health Administration (OSHA) exposure limits for nuisance dust are 5
mg/m3
(respirable dust) and 15 mg/m3
(total dust). The American Conference of Governmental
Industrial Hygienists (ACGIH) Threshold Limit Values (TLV) are 10 mg/m3
for inhalable particulates
(total dust) and 3 mg/m3
for respirable particulates (total dust) for Particulates Not Otherwise
Classified (PNOC).
 Consumer use of products containing ESCOREZ TACKIFYING RESINS – This category of
exposure is highly variable depending on the product being used and the conditions under which it is
used. Exposure of the majority of consumers is likely to be infrequent and of short duration.
Exposure could occur through the use of hot melt adhesive formulations that contain Escorez
Tackifying Resins. The best way to prevent exposure is to work in well-ventilated areas, wearing
chemical resistant gloves. Good personal hygiene practices should always be followed.
