A molding composition processable into a vulcanized elastomeric article such as a solid rubber tire, for example, is formed by mixing together previously vulcanized scrap rubber, a vulcanizing agent such as sulfur, and suitable quantities of accelerator and/or activator. The mixture is then vulcanized under heat and pressure. An alternatively preferred embodiment of the instant invention comprises the addition of a small amount of virgin rubber to the composition.

Molded composition and article molded therefrom

A process for producing thermoplastic, elastomeric articles such as, for example, semi-pneumatic tires, comprising the steps of admixing a thermoplastic, elastomeric molding composition including a vulcanizable or otherwise thermosetable elastomer, inert filler materials, a plasticizer and certain processing aids. The molding composition is then milled into a flat sheet, extruded into a tubular shape, cut, shaped and then molded at a temperature less than about 70.degree. F into thermoplastic elastomeric articles such as, for example, semi-pneumatic tires.
