Abstract

In prodn. of synthetic foam by mixing thermosetting plastic components and granulated thermoplastic material prior to foaming, a non-expanded thermoplastic with a vol. wt. of 500 - 1000 kg/m3 is mixed with a thermosetting plastic which on reaction produces sufficient heat to cause the thermoplastic granules to expand.
