This invention directs itself to a process for producing thermoplastic resin products where granulated or particulate vulcanized rubber is sprayed by a heated heavy paraffin distillate composition to form a first intermediate mixture composition. The first intermediate mixture composition is passed through a heating chamber (22) on a conveyor (20) and combined with particulate thermoplastic scrap material in an approximating weight percentage of 30% thermoplastic material to 70% first intermediate mixture material. The combination forms a second intermediate mixture composition which is masticated in a masticator (30) and extruded through a single screw feed mechanism (32) for palletizing and producing thermoplastic resin products which are useful for molding.
