ABSTRACT:
A process for producing a moulding from an expanded styrene polymer. This process comprises applying gas pressure to particles of the polymer, introducing the particles under pressure into a mould, and reducing the pressure to allow at least some of the particles to expand in the mould and bond together to form the moulding.
