ABSTRACT:
New and useful products are based on sheeted cellulose impregnated with a polyfunctional isocyanate and a fire retardant material. The fire retardants are chosen from organophosphorous esters compatible with the isocyanate in the proportions used. Preferred impregnating compositions use about one part of isocyanate and two parts of a halogenated diphosphate ester. Other compatible phosphorous based materials may be included for viscosity control.
