摘要 |
Viscoelastic polyurethane foam is prepared by using certain additives in the foam formulation. The additives include 1) alkali metal or transition metal salts of carboxylic acids; 2) 1,3,5-tris alkyl- or 1,3,5-tris (N,N-diaIkyl amino alkyl)- hexahydro-s-triazine compounds; and 3) Ci-12 carboxylate salts of quaternary ammonium compounds. The additives significantly improve processing and in particular permit the use of higher isocyanate indices, which helps to improve foam physical properties. |
