Low emission, cell opening surfactants for polyurethane flexible and rigid foams |
摘要 |
A method for preparing a polyurethane flexible molded or rigid foam by reacting an organic polyisocyanate with a polyol in the presence of urethane catalyst, water as a blowing agent, optionally a silicone surfactant cell stabilizer, and a cell opener characterized in that the cell opener comprises the reaction product of 1,1,1,3,5,5,5-hepta(hydrocarbyl)-trisiloxane coupled with polyalkyleneoxide mono allyl ether and capped with a C1-C20 hydrocarbyl group-containing succinic anhydride.
