Document Type and Number:
WIPO Patent Application WO/2022/194251
Kind Code:
A1
Abstract:
A composition for preparing a foam comprises (A) a polyol, (B) a pre-mixture comprising (B1) a silicone resin at least partially solubilized in (B2) a physical blowing agent capable of at least partially solubilizing the silicone resin (B1), (C) a polyisocyanate, and (D) a catalyst. The silicone resin (B1) includes at least 20 mol% (R 1
3SiO 1/2) siloxy units and at least 40 mol%of (SiO 4/2) siloxy units, each based on the total moles of siloxy units present in the silicone resin (B1), with the proviso that the combined amount of (R 1
3SiO 1/2) and (SiO 4/2) siloxy units is at least 85 mol%based on the total moles of siloxy units present in the silicone resin (B1), where each R 1 is independently a substituted or unsubstituted hydrocarbyl group.
