  • Isocyanate-terminated prepolymers and rigid-foams produced therefrom
    Patent number: 5962541
    Abstract: NCO-terminated prepolymers are made by reacting a polymeric diphenylmethane diisocyanate (PMDI) and a polyol having a functionality of from about 1.8 to about 4.0 and a molecular weight of from about 400 to about 2,000. The PMDI and polyol are reacted in amounts such that the equivalent ratio of isocyanate groups to hydroxyl groups is from about 15:1 to about 160:1. These prepolymers are useful in the production of polyurethane foams, particularly laminated foams.

  • Apparatus for the distribution of a foamable reaction mixture upon a moving base
    Patent number: 4945854
    Abstract: The present invention is directed to an apparatus for the distribution of a foamble reaction mixture upon a moving base. The present invention is directed to the discovery that by injecting small amounts of air into both ends of a conventional pipe-type dispenser, the operation time without any plugging can be substantially increased. The air flow prevents build-up of reaction mixture around the dispensing holes.
