A polymer modifying agent for use in increasing the shelf life of natural rubber. The polymer modifying agent consists of a zeolite, a high molecular weight fatty acid, a starch, a catalyst, and rubber processing oil and aliphatic resin. The compound bonds with the rubber, particularly the polymer chains of the rubber being encapsulated by the zeolite, preventing the aging effect caused by oxidation and light. The compound also acts to disperse the silica evenly throughout the rubber. The inventive compound is also composed of components that are non-toxic. A method of blocking the effects of premature curing of rubber is also provided. The method includes a step of adding the inventive compound to the rubber.
