POLYURETHANE FOAM STABILIZERS |
摘要 |
Polyurethane foam formulations contain stabilizing silicone surfactant compositions which include a first silicone characterized by having from about 2 to about 205 siloxane repeat units and which includes at least one substituent which is a polyhydric organicgroup (R<2>), an ester, ether, acetal or ketal derivative of a polyhydric organic group (R<3>) or a phenolic group (R<4>). The first silicone structures can be easily tailored for different types of foam formulations. The surfactant may optionally also include a second silicone selected from the group consisting of a silicone oil and a polyether silicone copolymer, in an amount which does not exceed 50 % of the total weight silicone surfactant in the surfactant composition.
