This invention relates to fire-resistant, flexible, molded, medium density polyurethane foams. These foams typically have a density of from 10 to 30 pcf. The foams are the reaction product of a) at least one polyester polyol, b) at least one highly branched polyether polyol, c) at least one chain extender, d) a polymethylene poly(phenyl isocyanate), an isocyanate group containing prepolymer based on a polymethylene poly(phenyl isocyanate), or mixtures thereof, e) a solid flame retardant and f) water. This invention also relates to a process for preparing these polyurethane foams in open molds.

Decorative molded foams with good impact resistance and fire retardant properties

Fire-resistant, medium density molded polyurethane foams which may be removed from a mold in substantially shorter times than previously possible are produced by the process of the present invention. These reduced de-mold times are achieved by including a solid flame retardant composition in the polyurethane foam forming composition. This solid flame retardant composition includes a melamine coated ammonium polyphosphate and zinc borate.

The present invention relates to a method of making a coated substrate that requires a polyurethane/urea contact adhesive, and the coated substrates produced by this method. This invention requires a) a polyisocyanate with a functionality of less than about 4, b) optionally, a polyol blend consisting of about 95 to 100% polyether polyols with molecular weights from about 1800 to 12000 and average functionality from about 1.5 to about 4 and up to about 5% of chain extenders with molecular weights from about 60 to 400 and average functionality from about 1.5 to about 3, and c) polyethers having at least two isocyanate reactive groups and a molecular weight of from about 1800 to about 12000 and average functionality from about 1.5 to about 4 in which at least 50% of the isocyanate reactive groups are primary and/or secondary amino groups. The weight ratio of components b) to component c) ranges from about 95:5 to about 0:100, and the amounts of components a), b), and c) are such that the equivalent ratio of isocyanate groups to isocyanate-reactive groups is from about 85:100 to about 115:100 and the sum of the urethane group content plus the urea group content is from about 1 to about 12%.
