  • Composition for manufacturing polyurethane foam and molded article thereof
    Patent number: 10189966
    Abstract: Disclosed are a polyurethane composition, a molded article, and a vehicle comprising the polyurethane composition or the molded article. The polyurethane composition comprises a polyol composition (A) in which polyether polyol (a1) and polymer polyol (a2) are mixed at a predetermined amount, an isocyanate composition (B) obtainable by polymerizing polyether polyol (b2) and an isocyanate composition (b1) that comprises i) methylene diphenyl isocyanate (M-MDI) and ii) polymethylene diphenyl isocyanate (P-MDI). As such, the molded article such as a vehicle seat pad can be manufactured with improved static and dynamic comfort.

  • FLAME RETARDED SLABSTOCK POLYURETHANE FOAM COMPOSITION FOR FLAME LAMINATION
    Publication number: 20150266993
    Abstract: The present disclosure provides a flame retarded slabstock polyurethane foam composition for flame lamination, which does not need to add a separate flame retardant additive because the polyurethane itself has flame retardancy. The flame retarded slabstock polyurethane foam composition for flame lamination according to the present disclosure, wherein the foam itself has flame retardancy by comprising methylene diphenyl diisocyanate (MDI), polymethylene diphenyl diisocyanate (PMDI), or a mixture thereof as an isocyanate compound, thereby obtaining an epochal effect that it does not need to add a separate flame retardant and an effect of solving a problem that physical properties of the conventional flame retarded slabstock polyurethane foam composition are reduced by adding a flame retardant.
