General pentane (hereafter, pentane) is a colorless, volatile and flammable liquid with a sweet or gasoline-like odor. Pentane consists of three isomers: n-pentane (the most important isomer), isopentane, and neopentane. n-Pentane is a constituent of crude oil and a component of the condensate from natural gas production. It is primarily obtained by fractional distillation of a petroleum stream (generally light virgin naphtha) obtained from the processing of crude oil. n-Pentane is used as a component of gasoline blends, as an aerosol propellant, in low temperature thermometers, as a blowing agent for foams (e.g. expandable polystyrene (EPS) and polyurethane (PUR)), and as a solvent (EU 2003). Isopentane is also used as a blowing agent, and neopentane is used in the manufacture of butyl rubber (ACGIH 2001).
Cyclopentane is a FLAMMABLE LIQUID and a FIRE HAZARD. IDENTIFICATION Cyclopentane is a clear liquid. It is used as a laboratory reagent, a solvent, and as an extraction agent in the paint and shoe industries. REASON FOR CITATION * Cyclopentane is on the Hazardous Substance List because it is cited by ACGIH, DOT, NIOSH, NFPA and EPA.

Watery colorless liquid with a gasoline-like odor. * All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details. As Pentane; there is no specific OSHA PEL for 2-Methylbutane. CAS #: 78-78-4 Formula: C₅H₁₂
A blowing agent blend for making polyolefin foams comprising isopentane and at least one co-blowing agent The co-blowing agent is either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof The blowing agent blend comprises less than about 99 mol % isopentane. A polyolefin foam structure prepared by the process comprising: melting a thermoplastic polyolefin polymer, dissolving an effective amount of a blowing agent blend in the polyolefin polymer, the blowing agent blend comprising less than about 99 mol % isopentane and at least one co-blowing agent, the co-blowing agent being either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof, forming an extrudate, transferring the extrudate to an expansion zone, and permitting the extrudate to expand in the expansion zone to produce the polyolefin foam structure, the polyolefin foam structure being a substantially closed-cell and dimensionally-stable structure. A process for making a polyolefin foam structure comprising: melting a thermoplastic polyolefin polymer, dissolving an effective amount of a blowing agent blend in the polyolefin polymer, the blowing agent blend comprising less than about 99 mol % isopentane and at least one co-blowing agent, the co-blowing agent being either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof, forming an extrudate, transferring the extrudate to an expansion zone, and permitting the extrudate to expand in the expansion zone to produce the polyolefin foam structure. A blowing agent blend for foaming low density polyethylene foam consisting essentially of isopentane and at least one co-blowing agent, the co-blowing agent being either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof, and wherein the blowing agent blend includes from about 10 to about 99 mol % isopentane and the remainder consists essentially of the co-blowing agent. The blowing agent blend of claim above, wherein the co-blowing agent includes at least one physical co-blowing agent, the at least one physical co-blowing agent being ethane, n-propane, n-butane, isobutane, cyclopropane, nitrogen, argon, carbon dioxide, sulfur hexafluoride, nitrous oxide, dimethyl ether, 1,1-difluoroethane (HFC-152a), 1,1,1-trifluoroethane (HFC-143a), 1,1,1,2-tetrafluoroethane (HFC-134a), 1,1,2,2-tetrafluoroethane (HFC-134), 1,1,1,3,3-pentafluoropropane (HFC-245fa) or combinations thereof.
Presently, physical blowing agents more commonly used for making low density polyethylene (LDPE) foams are hydrocarbons such as isobutane or blends of isobutane and n-butane. Other hydrocarbons such as ethane and propane have been used more recently in making LDPE foams. The ability of isobutane, n-butane, propane, ethane and combinations thereof to give stable, low density foams depends on factors such as desirable solubility in low density polyethylene, and the ability of gas permeation modifiers to slow down the escape of such blowing agents. The resultant foam article (e.g., a sheet) using such blowing agents is frequently produced with at least some corrugation. Corrugation occurs when the radial rate of expansion is higher than the radial space available for the foam as it exits the die. Corrugation may be reduced to a certain extent by optimizing the foaming process and apparatus used in forming the foam with these blowing agents, but a low degree of corrugation or visible corrugation lanes often remain. The corrugation becomes more pronounced when a fluid with a very low boiling point (e.g., ethane or propane) is (a) used as the sole blowing agent or (b) present in an amount greater than about 5 mol % with a higher boiling fluid (e.g, isobutane). Corrugation also tends to occur more frequently in sheets (thickness of up to about ½ inch) as opposed to planks (thickness of greater than about an inch), and the degree and magnitude of corrugation increase as the foam density decreases. According to one embodiment of the present invention, a blowing agent blend for making polyolefin foams comprises isopentane and at least one co-blowing agent. The co-blowing agent is either a physical co-blowing agent having a boiling point less than 28° C., or a chemical co-blowing agent, or combinations thereof. The blowing agent blend comprises less than about 99 mol % isopentane. The polyolefin foam may be a low density polyethylene foam. The blowing agent blend may consist essentially of isopentane and the co-blowing agent in which the blowing agent blend includes about 10 to about 99 mol % isopentane with the remainder consisting essentially of the co-blowing agent.
Dearomatic Solvents Market
De-aromatic solvents, also called de-aromatized hydrocarbon solvents or ultra-low aromatic solvents, are a class of hydrocarbon solvents that are characterized by the presence of paraffinic, iso-paraffinic, and naphthenic components, with very low aromatic content (<1%).

A growing paints, coatings, and inks industry worldwide.
n -Hexane is a chemical made from crude oil. Pure n -hexane is a colorless liquid with a slightly disagreeable odor. It evaporates very easily into the air and dissolves only slightly in water. n -Hexane is highly flammable, and its vapors can be explosive.
2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C₆H₁₄. It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain. Using a quantitative structure-activity relationship prediction model, 2-Methylpentane has a research octane number of 75, motor octane number of 77, and cetane number of 29.
n-Heptane is a colorless liquid with a mild, Gasoline-like odor. It is used as an industrial solvent and in petroleum refining processes. REASON FOR CITATION * n-Heptane is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, IRIS and NFPA.
n-Octane is used as a solvent and raw material for organic synthesis reactions and is a very important chemical in the petroleum industry.
