Title:
EXPANDABLE COMPOSITION FOR NON-FLAMMABLE POLYURETHANE FOAMS
Document Type and Number:
WIPO Patent Application WO/2020/110332
Kind Code:
A1
Abstract:
The present invention provides an expandable composition which is capable of advantageously forming a non-flammable polyurethane foam that has synergistically enhanced flame retardancy. The present invention also provides an expandable composition which is capable of advantageously forming a non-flammable polyurethane foam that has an enhanced degree of freedom in coloring without losing the color of a polyurethane resin itself. According to the present invention, an expandable composition for polyurethane foams, which contains a composition A containing a polyol, a composition B containing a polyisocyanate and an expanding agent, is configured to contain, as a catalyst, at least a trimerization catalyst, while being configured such that at least one of the composition A and the composition B contains an organic metal phosphinate salt in an amount of 30 parts by mass or more relative to 50 parts by mass of the polyol.
