Major reduction in chemical curatives for rubber articles

The sulfur cure system in the ethylene-propylene-diene (EPDM)-based Curtain Wall Seal (CWS) has two accelerators, adding up to 2.75 parts per hundred rubber (phr) by weight, and two activators (ZnO: 5phr, stearic acid:1phr). In total, 8.75phr chemicals are used to fully cure the article with 1phr elemental sulfur. Excessive use of chemical curatives is harmful to health, safety, and the environment. A new method uses experimental results from high temperature cure tests to provide highly efficient cure systems for industrial rubber articles, which requires a lot less chemical curatives without compromising cure efficiency. This method can be applied to reduce chemical curatives in other industrial rubber articles.
