Polystyrene or EPS for short, is a lightweight, rigid, plastic
foam insulation material produced from solid beads of
polystyrene. A cost-effective, easy-to-use and process material,
it performs as an acoustic and thermal insulator, is moisture
resistant, recyclable and environmentally sound.
polystyrene foam (EPF) is a plastic material that has special
properties due to its structure. Composed of individual cells of
low density polystyrene, EPF is extraordinarily light and can
support many times its own weight in water.
