Abstract

Non-shrinkage epoxy resin foams are formed by adding to 99.9-3 wt.% epoxy resin, 0.1-97wt.% physical blowing agent, as blowing agent contg. polystyrene beads. The mix is heated to 50-180 deg.C. - The foamed product shows no shrinkage, has limited thermal expansion, decreased density and in comparison with epoxy resins foamed by chemical means, exhibits improved physical mechanical properties.
