MIX OF SILICON-POLYETHER COPOLYMER SURFACTANTS AS PU FOAM CELL OPENERS

摘要

Compositions including silicone surfactants of the type used in manufacturing urethane foams and certain siloxane-oxyalkylene copolymers which act as cell openers when employed in combination with silicone surfactants in urethane foam manufacture are disclosed and claimed, as are urethane foam compositions including such cell openers, a method of preparing urethane foams using such cell operers. and urethane foams prepared by the method.
