Abstract
An organo-metallic compound for use as a chemical aid in using scrap plastics in rubber formulations. The organo-metallic compound includes a zeolite, a starch, and a high molecular weight fatty acid soap. The compounds are in powder form and mixed together by a high-speed blender. The inventive compound creates a bridge between the scrap plastic and the rubber formulation allowing a blend between the two compounds. The compound accomplishes this while using a non-toxic substance. A method for using scrap plastics in rubber formulations is also provided. The method includes the step of adding the inventive compound to the scrap plastic and the virgin rubber.
