Abstract:
1. A polyurethane foam forming composition delivery system comprising: a container; a pressurized single component polyurethane foam forming composition comprising a mixture of (a) prepolymers containing free isocyanate groups in the range of 12 to 17 percent by weight, based on the prepolymer, which is produced by reacting a polyisocyanate with a polyol blend comprising a first polyol that is a triol having a molecular weight of in the range of from 600 to 2500 and a second polyol that is a diol, triol, or mixtures thereof having a molecular weight in the range of from 6000 to 10,000, wherein the first polyol and the second polyol are present in a parts by weight ratio in the of from 1:6 to 1:2; (b) a blowing agent; and (c) from 0.5 to 4 percent by weight a surfactant comprising the reaction product of a poly(alkyl siloxane) and a poly(alkylene oxide) copolymer, where the alkylene oxide are ethylene oxide, propylene oxide or butylene oxide, based on the total weight of the single component polyurethane foam forming composition, and
