<p>Fire retardant materials are prepared by treatment of foams with a dispersion of polyvinylidene chloride antimony oxide and a binder. A covering layer of such a material may impart fire resistance to underlying materials, and may be used in bedding, furniture and clothing. Typical materials which may be treated include polyurethane foam, polyesterurethane, polyetherurethane foam, polyvinylchloride foam, foam rubber and polyester fibre. These may be applied as backing to a covering material or applied to an interlinear disposed between a filling material and a covering material.</p> |
