ABSTRACT:
A method for producing a flexible polyurethane foam from reacting a polyol blend with a polyisocyanate in the presence of a polyurethane formation catalyst is described. The polyol blend contains from 0.5 to 10 wt. % of an aromatic polyester polyol extender typically used in rigid foams. The polyol extender is made from dibasic acids, alkylene glycols and recycled polyethylene terephthalate. Commercial extenders cause flexible foams to shrink, a problem not found in the foams of this invention.
