Name: Expanded Polystyrene
Chemical properties: Expanded Polystyrene or polystyrene is made from styrene by suspension polymerization, adding foaming agent. White pearl particles, the relative density of 105, low thermal conductivity, water absorbing pieces, impact and vibration resistance, heat insulation, sound insulation, moisture-proof, shock absorber, Excellent dielectric property, soluble in acetone, benzene, toluene, ethyl acetate, ethylene dichloride, chloroform, ethanol, not soluble in hexane, cyclohexane, solvent gasoline.
Uses: Expanded Polystyrene is a hard cell foam material of polystyrene EPS has good thermal insulation and shock absorption, high compression strength, light weight and moisture resistance, EPS is a polystyrene ( PS ) hard cell foam material, has good thermal insulation and shock absorption, high compression strength, light weight and moisture resistance, mainly used for building wall, roof insulation, thermal insulation composite board, cold storage, air-conditioning, vehicle, ship insulation, floor heating, decoration sculpture and other extensive uses.
Health hazards:  basic non-toxic polymer. Environmental hazards:
Explosion risk:  Expanded polystyrene is flammable, irritating.
Hazardous characteristics: Expanded Polystyrene Powder can form explosive mixtures with air, when Expanded Polystyrene reaches a certain concentration, and it will explode when encounters flame. Expandable Polystyrene EPS will decompose to produce flammable gas when heated. Harmful products of combustion are carbon monoxide, carbon dioxide.
Storage note: Expanded Polystyrene EPS is Stored in a cool treasury with ventilation. Away from fire, heat source should be stored separately from oxidant, avoid mixing reservoir equipped with the appropriate variety and quantity of fire equipment. Storage areas should be equipped with appropriate materials to store leakage.
