Expanded Polystyrene (EPS) vs. STYROFOAM™ Brand Foam

Polystyrene cups and sheets

A common question we hear all the time is, “What’s the difference between Expanded Polystyrene Foam and STYROFOAM Brand Foam?” Some times, people are looking for expanded polystyrene foam products, but mistakenly refer to them as STYROFOAM, even though the materials are completely different.

Expanded Polystyrene (EPS)

Most common “foam” products, like coolers, wine shippers, molded end caps and corners, box packaging and even cups at the office water cooler are actually polystyrene foam. Expanded Polystyrene (EPS) is the generic industry name for the white rigid material made by expanding polystyrene beads with steam and pressure to bond the beads together to form blocks or to shape molds. EPS is also used in the construction industry for insulation and void fill.
