Abstract

Compositions for the formation of temperature resistant, tough, flame retardant polyurethane foams, comprising a low VOC polyisocyanate component wherein the isocyanate is a low functionality isocyanate; a low VOC active-hydrogen containing component substantially reactive with the low functionality isocyanate to form a polyurethane; a surfactant composition; and a catalyst component, wherein the total mass loss of the foam is less than 1% by weight as measured by ASTM E595. The foams are useful as gasketing materials, for example.
