Abstract

Abstract The results of research on the development of a polymer composite material from a two-component polyurethane compound for the manufacture of foundry equipment for the production of gasified models and other products from expanded polystyrene by blowing with hot steam are presented. The requirements for the material of the molds in terms of heat capacity and thermal conductivity are indicated. Selected additives in the form of powders of copper, aluminum, iron and graphite. Samples of polymer composite materials were obtained. The research were carried out according to a specially developed technique based on the well-known method for determining thermophysical properties by eliminating variables. The result is a composition based on a polyurethane compound with 54.5 wt.% aluminum powder, meeting the specified requirements for both technological and thermophysical properties.
