A method is disclosed for flatproofing a tire and wheel assembly with a flexible, lightweight foam-fill by supplying at least two polyurethane reactive materials to a static mixer. The static mixer mixes the reactants, and a nucleating gas is supplied to the mixed reactants in the static mixer to form a liquid reactant mixture with entrained gas. The reactant mixture is injected into the tire and wheel assembly where the mixture reacts and foams replacing the air in the tire with a flexible, lightweight semi-open cell foam-fill. The resulting foam-filled tire and wheel assembly is then allowed to cure.

There is disclosed a carpet product. The carpet product comprises a polymer-coated carpet backing, a layer of silicate on the polymer-coated carpet backing, and a layer of polyurethane on the layer of silicate. A method of producing the carpet product is also disclosed.

Sodium silicate coating process and products incorporating same

The present invention relates to a method and apparatus for forming a layer of blown cellular polyurethane on a textile material, such as a carpet backing. The method includes applying to a textile material a layer of reactive polyurethane forming agents containing a sufficient amount of water or heat-sensitive blowing agent so as to cause chemical blowing of the mixture when heated sufficiently, heating the layer so as to cause chemical blowing of the mixture and applying to the layer during the chemical blowing thereof a pressure of an amount and for a time sufficient to control the blowing of the mixture to a desired degree, the pressure being applied to the mixture continuously from an initial pressure to a final pressure, wherein said initial pressure is greater than the final pressure. Apparatus for performing the process is also disclosed.

Polyurethane coating system

An improved process for the manufacture of polyurethane elastomers from a reaction mixture which comprises a polyol, an isocyanate, water, a bismuth catalyst and an optional filler. In the improved process of this invention, the rate of reaction is decreased by the addition of water to the reaction mixture and increased by the removal of water from the reaction mixture.
