    摘要： Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone.

    摘要： Methods and combinations of a curing catalyst with a mold release mixture, which is then subsequently applied to the surface of a mold prior to the application of polyurethane reactants to said mold, where the curing catalyst component has the effect of catalyzing the reaction at the surface of the molded part. This catalysis results in greater reactivity at the surface between reacting portions and lower delamination of the surface of the foam, thereby leading to more attractive skins with a more consistent cell structure, and lower de-mold times due to skins whose nature makes them less likely to adhere to the surface of the mold. These foams will be less likely to tear upon opening of the mold, and production quality and output will be improved.
