  • Patent number: 9822213
    Abstract: A method of forming a flame resistant flexible polyurethane foam that has a V-0 rating, according to Underwriters Laboratories Standard 94 Flammability Test, includes forming a reaction mixture that has an isocyanate component and an isocyanate-reactive component, and the isocyanate-reactive component includes a polyol component. The isocyanate component includes at least 30 wt % of a biuret modified aromatic diisocyanate, based on a total weight of the isocyanate component, and an isocyanate index of the reaction mixture is less than 100. The polyol component includes at least 5 wt % of a filled polyether polyol and at least 65 wt % of one or more other polyols that are different from the filled polyether polyol, based on a total weight of the isocyanate-reactive component.

  • Patent number: 9765477
    Abstract: Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.

  • Patent number: 8883934
    Abstract: Flexible polyurethane foams that function well in noise and vibration absorption applications are made from a mixture of polyether polyols oxides that each has a hydroxyl equivalent weight of from 1200 to 3000 and at least 70% primary hydroxyl groups. From 5 to 80% by weight of the ethylene oxide-capped polypropylene oxides are nominally difunctional, from 0.5 to 20% by weight of the ethylene oxide-capped polypropylene oxides have a nominal functionality of four or higher, and the balance of the ethylene oxide-capped polypropylene oxides, but not less than 1.5% by weight thereof, are nominally trifunctional.

  • Patent number: 5290636
    Abstract: Improved flame retardant latex coatings are disclosed which comprise copolymers of ring-halogenated aromatic monomer units and alkyl acrylate/methacrylate monomer units, and which may additionally include at least one other monomer. In a first embodiment, the coatings include ring-brominated aromatic monomer units and alkyl acrylate and/or alkyl methacrylate monomer units. In a second embodiment, the coatings include these first two types of monomer units and further include third monomer units from unsaturated esters of saturated carboxylic acids, halogen-free aromatic monomers or unsaturated carboxylic or dicarboxylic acid monomers. In a third embodiment, the coatings include four monomer units, namely ring-brominated aromatic monomer units, alkyl acrylate/methacrylate monomer units, halogen-free aromatic monomer units and unsaturated carboxylic or dicarboxylic acid monomer units.

  • Patent number: 5219936
    Abstract: A preferred rigid thermoplastic resin composition having high impact strength and resistance to thermal distortion includes a vinyl chloride resin/polycarbonate alloy and at least 3 parts by weight of butadiene-modified acrylic per 100 parts by weight of the alloy. A particularly preferred thermoplastic resin composition includes the alloy and both butadiene-modified acrylic and ethylene-vinyl acetate copolymer.
