Foamex - Innovative Polystyrene

Foamex expanded polystyrene (polymerised styrene) is a rigid cellular plastic foam material derived from petroleum and natural gas byproducts. Styrene is produced from benzene and ethylene, and is polymerised in the presence of catalysts, usually organic peroxides. The beads of resin are subjected to steam, which causes the thermoplastic polystyrene to soften and expand up to 40 times its original volume. Each small bead of polystyrene is fully sealed.

No chlorofluorocarbons (CFCs) are contained in, nor are they used in the manufacture of Foamex EPS.

Once conditioned by ageing, the EPS beads are blown into a mould, and steam is used in the forming process. The EPS product is then dried and finished by a number of processes, such as hot wire cutting or lamination.
