The expanded foam (known as EPS) is produced as small beads containing a pentane blowing agent which is expanded by treatment with steam to form pre-foam of the required density. The pre-foam is then fed into moulds and more heat (steam) is applied. This heat fuses the beads together to produce items in a variety of shapes and sizes or to make blocks for cutting into sheets and other products.
