Document Type and Number:
WIPO Patent Application WO/2012/105657
Kind Code:
A1
Abstract:
A hard foam having good properties can be produced by reacting a polyol composition with a polyisocyanate compound in the presence of a foaming agent, a foam control agent and a catalyst, wherein a hydrofluoroolefin is used as the foaming agent. The foaming agent comprises a hydrofluoroolefin (I) represented by the formula: R1CH=CHR2 (wherein R1 represents a perfluoroalkyl group having 1-6 carbon atoms, and R2 represents a perfluoroalkyl group having 1-6 carbon atoms or a halogen atom). The polyol composition to be used is any one of three types of compositions [i.e., a polyol composition (Pa), a polyol composition (Pb) and a polyol composition (Pc)], each containing polymer particles.
