Abstract
A heat and pressure moldable material end product made from injection or extrusion molding processes using a mixture of reclaimed pre-vulcanized rubber bits and resinous thermoplastic material bits as raw material. The reset end product is a homogeneously incomplete mixture of the raw material, including reset resin and rubber mixture portions and rubber bits per se in a bonded inter-relationship. The porosity of the end product is controllable by the relative amount and size of rubber particles in the raw material mixture.
