  • Ternary flame-retarded compositions including iron oxide
    Patent number: 4033916
    Abstract: New flame-retarded rubber and plastic compositions are disclosed which are economical to produce and which exhibit increased flame-retardance, improved mechanical properties and reduced toxicity. Generally, these new compositions comprise a copolymer of acrylonitrile-butadiene rubber or a terpolymer of acrylonitrile, butadiene and styrene, a bromine- or chlorine-containing organic fire-retardant additive, and an iron oxide.
    Type: Grant
    Filed: September 10, 1975
    Date of Patent: July 5, 1977
    Assignee: Uniroyal Inc.
    Inventor: William Paul Whelan, Jr.
  • Flame retardant polymer compositions
    Patent number: 3998783
    Abstract: Polymers are flame-retarded by novel combinations of additives comprising:A. a specified compound of iron, cobalt, nickel, tin or antimony,B. an alkali metal chloride, bromide or iodide, andC. an organic acid or inorganic acid salt. Alternatively, additive (c) may be an integral part of the polymer in whole or in part.
