摘要: Disclosed is a foamed polymeric material comprising continuous phase of polyurethane having solid polyvinyl chloride particles dispersed therein. The preferably comprises about 100 parts foamable urethane, and 10 to 50 particle size below 200 microns. has microcellular structure with cells on the order 0.1 mm in average diameter or less. walls comprise matrix reinforced PVC particles. may be used as wood substitute.
