COMPATIBILIZATION OF BLOWING AGENT POLYOL MIXTURES FOR POLYURETHANE FOAM MANUFACTURE

摘要

Provided herein are subcombinations from which polyurethane foams and polyurethane foams containing polyisocyanurates may be prepared. The subcombinations are unique in that they contain components which synergistically act towards promoting compatibility between a blowing agent and the remaining components of the formulation. Through the use of the teachings herein, blowing agent concentrations in excess of 25 % by weight of the total subcombination may be incorporated.
