Title:
PROCESS FOR MAKING LOW DENSITY FOAMS, POLYOL COMPOSITION AND REACTION SYSTEM USEFUL THEREFOR
Document Type and Number:
WIPO Patent Application WO2000073362
Kind Code:
A3
Abstract:
The invention relates to a polyol composition comprising by weight 60-97 % of b1) a polyoxyethylene-polyoxypropylene polyol, having a functionality of 2-6 with 10-25 % tipped EO; 3-40 % of b2) a polyoxyethylene-polyoxypropylene polyol, having a functionality of 2-6, with 20-50 % total EO and 10-20 % tipped EO; and 0-25 % of b3) a polyol, having a functionality of 2-6, with at least 50 % random EO. The invention also relates to a process for preparing a flexible polyurethane foam by reacting a) a polyisocyanate composition; b) a polyol composition of the invention; c) water; and d) additives and auxiliaries known per se. The invention finally relates to a reaction system comprising A) a polyisocyanate and B) an isocyanate-reactive component comprising the polyol of the invention.
