Abstract
Flexible polyurethane foams based on a blend of polyether and polyester polyols are described. The polyurethane foams of the invention have at least one of (a) enhanced pourability of a predominantly polyether foam; (b) flame laminability to a predominantly polyether foam without having as an essential ingredient an additive; (c) improved flame retardancy of a predominantly polyether or polyester foam; (d) improved hydrolytic stability to a predominantly polyester foam, or (e) increased softness to a predominantly polyether or polyester foam.
