POLYURETHANE FOAM MATERIAL

摘要

A polyurethane foam material comprises polyol (polyether) and isocyanate components, catalysts, surfactants (foam stabilizers), natural components. The material comprises polyesters and polyethers as polyol component, amine catalyst tris-(dimethylaminomethyl)phenol and organo-tin catalyst tin octoate are used as catalysts. It comprises block copolymer of polydimethylsiloxane and alkylene oxides and paraffin oil as surfactants (foam stabilizers), and polysaccharides as natural component.
