Abstract:
A synthetic, compression molded floor covering material comprising:a) about 15% by weight of an elastomeric binder essentially consisting of a mixture of i) ultra low density polyethylene; and ii) ethylene vinyl acetate obtained from recycled rubber from shredded vehicle tires; b) about 50% by weight of a mixture comprising high density polyethylene, recycled crumb rubber, and, optionally, styrene butadiene rubber and/or ethylene propylene diene monomer; c) about 20% by weight aluminum trihydrate fire retardant; and d) an additional about 10% by weight high density polyethylene, wherein the above materials have been blended together at a temperature in the range of 280-320Â°F. to form a homogeneous blend, extruded at a temperature below 350Â° F., and then molded in a compression mold of a desired configuration at a temperature in the range of 160-325Â° F.
