Abstract
Process for the manufacture of molded bodies in plastic foam, characterized essentially by the fact that in a first phase the colorless particles of 0.2 to 3 mm of material, composed of pure polystyrene with an agent that facilitates the expansion, are subjected to a pre-expansion process that can be carried out either in a steam stream or atmosphere up to 110º C, or in hot water with temperatures between 80 and 110º C, either in hot air flow or under the action of heat radiations of any kind, in a given time inversely proportional to the desired densities, which can vary from five seconds to 15 minutes.
