Thermoplastic compositions and methods

Abstract

A new composition is formed by combining a reduced waste rubber, a heavy paraffin and a reduced waste thermoplastic, and then further reducing the resulting material while holding it at an elevated temperature. In preferred embodiments the rubber and thermoplastic are pre-processed by reduction to mesh sizes of about 0.25 inch and 0.5 inch respectively, and the paraffin is pre-processed by being fluidizing to have a viscosity of at most about 1.0 Centipoise. It is also contemplated that the rubber and paraffin can be advantageously combined with each other prior to inclusion of the thermoplastic, with the paraffin/rubber combination being heated to a temperature of about 220° F. to about 250° F. for about 3 minutes. It is still further contemplated that the combination of rubber, paraffin and thermoplastic can be heated to between about 360° F. and about 500° F.
