ABSTRACT:
A process for extruding a mixture of thermoplastic and ground whole tire waste, in which the mixture is extruded through a die to form an extrudate, with the extrudate subsequently cooled by directing a cooling gas toward the extrudate top, bottom and sides from a multiplicity of gas jets positioned around the periphery of the extrudate. In addition to an extruder, the apparatus includes a multiplicity of gas jets adjacent the extruder, positioned to direct a cooling gas toward the extrudate top, bottom and sides.
