Abstract
A rubber-processing additive for use in bridging rubber grind and virgin rubber. The rubber-processing additive consists of a zeolite, a high molecular weight fatty acid, and a starch. The compound binds the rubber grind to the virgin rubber. The inventive compound is also composed of components that are non-toxic. The compound does not significantly affect the physical properties of the virgin rubber. A method for using a rubber-processing additive to bind rubber grind to virgin rubber is also provided. The method includes the step of adding the inventive compound to a mixture of rubber grind and virgin rubber.
