(57) [Summary] [Structure] (A) Dimethylpolysiloxane-polyoxyalkylene copolymer, (B) General formula R 3 SiO 1/2 (wherein R is the same or different from each other and has 1 to 1 carbon atoms) There is provided a foam stabilizer composition comprising a toluene-soluble organosilicon compound having (6) an unsubstituted or substituted monovalent hydrocarbon group) and a SiO 4/2 unit as a main constituent unit. [Effect] By using the foam stabilizer composition, the amount of Freon R-11 used as a foaming agent can be reduced or not used, or Freon R-22, instead of Freon R-11, can be used. A good polyurethane foam can be produced by using an alternative CFC such as R-141b. |
