摘要
A perfected process for the production of expanded plastic materials, comprising a hot moulding phase of a starting polymeric blend inside a mould, wherein the heating of said blend is effected by making the same a heat source, by triggering an exothermic reaction in its interior. With respect to the known art in the field, the process of the invention allows an improvement in the heating of the polymeric mass inside the mould, reducing the times necessary for effecting it and homogenizing the thermal values inside this mass.
