  • Intumescent flexible polyurethane foam
    Patent number: 4374207
    Abstract: Flexible, resilient, polyurethane foam having improved flame retardancy and intumescent properties is prepared from a reaction mixture comprising a polyether polyol, an organic polyisocyanate, a blowing agent, a surfactant, a catalyst, a flame retardant, and hydrated alumina. Alternatively, the mixture also comprises a low-viscosity linear polyester.The hydrated alumina is predispersed in a mixture comprising flame retardant and low-viscosity linear polyester, and alternatively a char former and a fugitive viscosity modifier.

  • Process for a polyurethane foam containing fragrance
    Patent number: 4226944
    Abstract: Fragrance-emitting articles comprising a polyurethane foam containing a particulate filler and a fragrance material, and a method of making such articles, are disclosed. The method includes the essential steps of pre-mixing particulate filler and fragrance and dispersing the pre-mix in a liquid polyol, before adding the other reaction mixture components, and provides a polyurethane foam having a controlled rate of release of the fragrance.

  • Production of polyurethane foam of reduced tendency to form embers when burned
    Patent number: 4139501
    Abstract: Flexible polyurethane foam having reduced tendency to form burning embers when it is ignited and burned is provided by incorporating into the reaction mixture before foaming a derivative of melamine wherein one or more hydrogens have been replaced by hydroxymethyl and/or lower alkoxymethyl groups.In one embodiment, flexible polyurethane foams of increased flame retardance are also provided, by also incorporating a halogenated phosphorus ester into the reaction mixture before foaming.
