Title:
POLYURETHANE FOAMING COMPOSITION AND METHOD FOR PRODUCING FLEXIBLE POLYURETHANE FOAM
Document Type and Number:
WIPO Patent Application WO/2013/161854
Kind Code:
A1
Abstract:
Provided is a polyurethane foaming composition which includes polyisocyanate (A), an active hydrogen-containing compound (B) including polyol (B1) and water (B2), a catalyst, and a cross-linker composition (C). The cross-linker composition (C) includes at least one cross-linking agent (C1) selected from an ethoxylate derivative having Mw of 2000 or less (CA) and an ester compound having Mw of 2500 or less (CB), and a polar aprotic solvent (C2), in which the mass ratio ((a+b)/c) of c which is the content of the polar aprotic solvent (C2) to the sum of a which is the content of the ethoxylate derivative (CA) and b which is the content of the ester compound (CB) is 1/10 to 10/1. A flexible polyurethane foam exhibiting improved compressive residual stress under hot and humid conditions and providing excellent feeling is obtained.
