Normal Pentane(CAS 109-66-0) are highly effective blowing agents used in the production of Expandable Polystyrene (EPS) foam and other foams. Usually, a mixture of n-, i-, and increasingly cyclopentane is used for this purpose. Can be used as desorption agents formolecular sieve dewaxing technique when its purity exceeding 95%(wt). Because N-pentane is Extremely flammable, will form explosive mixture with air, may result in combustion and explosion if expose to source of heat or open fire. May explode when in heated container. React violently with oxidizing agent. It is heavier than air and insoluble in water, will spread to distant area at lower levels, and strike-back if come into source of ignition.
