Title:
FOAMABLE COMPOSITION FOR POLYURETHANE FOAM AND METHOD FOR PRODUCING POLYURETHANE FOAM BY USING THE SAME
Document Type and Number:
Japanese Patent JP2022032435
Kind Code:
A
Abstract:
To provide a foamable composition useful for forming a thick polyurethane foam in which the shrinkage of foam can be effectively suppressed.SOLUTION: A foamable composition causes a polyol composition and a polyisocyanate to react with each other by using at least a carboxylic acid metal salt catalyst, as a catalyst, to form a polyurethane foam by foaming with a foamer. The polyol composition contains, as polyols, a polyester polyol (A) and a polyether polyol (B) at a mass ratio of A: B=70: 30-40: 60. 70 mass% or more of the polyether polyol is composed of an ethylenediamine-based polyether polyol, and further contains polymer fine particles.SELECTED DRAWING: None
