    摘要: A polyurethane material comprising a hexamethylene diisocyanate (HDI) trimer and a polyol is disclosed. Content of oligomer, which is equal to or higher than a pentamer, in said HDI trimer is restricted to 0 to 50% by weight, and 3 to 10% by weight of monool is added to said HDI trimer. The polyurethane material is high in breaking elongation, superior in flexural resistance, and not subject to cracks or breaking.

    摘要: A semi-rigid integral skin foam having a low foamed integral skin layer and a highly foamed core is molded from a polyurethane formulation injected into a mold cavity having a reduced pressure of 400 Torr or below. The formulation comprises a polyol component, an isocyanate component, and at least one substance selected from among formic acid, an amine salt thereof and an amine salt of boric acid, while not containing any freon.

    摘要: A reaction-injected foam molding comprising a skin coating film formed by the in-mold coating method and having an elongation at break of 20-200% (JIS K 6400: No. 1 dumb-bell test specimen) and a urethane foam body obtained by reaction injection molding and having a density of 0.35-0.60 g/cm3. Said molding permits easy removal of flashes even though the urethane foam body is of a high ratio expansion with a density of 0.35-0.60 g/cm3.

    摘要: A material for producing a pad cover molding polyurethane, comprsing a polyol, an isocyanate and an urethane reaction retarding catalyst comprising a tertiary amine blocked with an acid such as formic acid, said material containing neither any fluorocarbon nor any chlorofluorocarbon. The polyurethane material according to the present invention is capable of molding a non-foamed or sparsely foamed lacuna-free pad cover although the material contains neither any fluorocarbon nor any chlorofluorocarbon.
