摘要：

An active filler composition utilizing scrap rubber, such as automobile tires, as a main or primary ingredient is used in the treatment, recycling, and manufacture of various rubber and plastic articles. A chemical plasticizer and binding agent is used in the production of the composition to plasticize, swell, and soften the scrap rubber. The filler composition is a homogeneous blend of from about 40 to 95 parts by weight of cured rubber particles and from about 5 to 60 parts by weight of the liquid plasticizer and binder. The active filler composition can be further compounded with materials such as polyethylene, polyethylene-terephthallate (PET), polyurethanes, urethanes, polyisocurates, polyacrylics, polyvinylchloride (PVC), and epoxies, to form a composite material for combining with still other materials to impart elastomeric properties. The product and process are particularly suitable for use with cryogenically produced rubber and provides an efficient method for recycling scrap rubber tires and converting them into useful commercial products.
