USE OF ORGANOSILOXANE COMPOSITIONS AS FOAM STABILIZERS IN FLEXIBLE POLYESTER POLYURETHANE FOAM |
摘要 |
A process for manufacturing low density flexible polyester polyurethane foam utilizing as a foam stabilizer selected low molecular weight (e.g., 400 to 1500) organosiloxane compositions containing monomeric units A, B and C wherein A is a monofunctional trimethylsiloxy unit [(CH3)3SiO1/2], B is a difunctional dimethylsiloxy unit [(CH3)2SiO2/2] and C is a difunctional organomethylsiloxy unit [R(CH3)SiO2/2] where R is a cyano-, ether-, hydroxy-or phenyl-organo modifying moiety, and in which the unit ratio of B to C in each organosiloxane composition is from 1 to 4 inclusive; solutions of such organosiloxane compositions; and the foams derived from such process. |
