Patent
CA 1336109
Synthetic mineral compositions, methods and articles are provided in which both high polishability and flame retardancy are achieved, by encasing a particulate flame retardant such as alumina trihydrate with a resin having like polishing characteristics to the synthetic organic polymers of the synthetic mineral. A polishable flame retarding synthetic mineral product is provided comprising a resin matrix, a particulate resinous filler distributed therein in a manner simulative of natural mineral markings, said matrix and filler having like polishing characteristics for a uniform gloss after polishing; and a flame retardant in a flame retarding effective amount, said flame retardant being harder and of different polishing characteristics than said matrix and normally tending to interfere with surface polishing to uniform gloss of said product, said flame retardant being completely encased within said filler particles in a manner blocking surface exposure of said flame retardant, whereby said product surface is polishable to a uniform gloss. This invention also comprises a method of flame retarding a composition; a method of manufacturing architectural articles of synthetic organic polymer which are frame retarded; a method of selectively modifying the properties of a composition; and a composition comprising a synthetic organic polymer matrix and a property modifying effective amount of a modifying agent.
