Abstract
Abstract 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.

Claims Analysis
Total Claims: 29
Claim 1
Independent Claim
118 words
A polishable, flame retarded, synthetic mineral product 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 which is harder and of different polishing characteristics than said matrix and normally tends to interfere with surface polishing of said product to uniform gloss, said flame retardant being first covered with a coating of said filler resin which is then cured separately for said matrix, and thereafter said coated flame retardant is added as filler particles into said matrix and the said flame retardant, whereby said product surface is polishable to a uniform gloss.
Claim 2
Dependent Claim
