Styrene of lower degree exists in nature and used to manufacture the EPS. Granules sugar size translucent round blobs of polystyrene are produced with polymerization process in which low boiling point hydrocarbon and pentene gas is used as supplementary for creation of EPS and it is derived from ethylene and benzene.
Expanded Polystyrene foam is manufactured from the by-products, or left overs, from the oil refining process. FPM is a “Block Molder” of EPS which means we mold EPS into large blocks 36” x 48” x 120” in size. These blocks are then cut into smaller usable sizes that vary with the application. The description below explains how FPM manufactures the EPS foam pieces and sheets you are familiar.
