Patent ID: 7838566

Claim:
A process for the preparation of polyurethane cold cure foams by reacting a mixture of polymer polyols optionally containing fillers with polyfunctional isocyanates, amines, crosslinking agents, catalysts, blowing agents and stabilizers, wherein the stabilizers used are siloxane compounds of the general formula (1) the proportion of siloxanes with N=(n+2)>9 being higher than 10% by weight and that with N>12 is present in amounts of 5 to 30% by weight, and that with N>22 is present in an amounts of up to 5% by weight; the fractions of linear (N<5) and cyclic siloxanes (D3 to D8) are present in amounts of up to 5% by weight wherein the % by weight is based on the total weight of the siloxanes; and wherein the solid content of the polymer polyols is from 5% to 40% by weight.
