  • Vulcanization Process for Rubber Products
    Publication number: 20230085729
    Abstract: A process for preparing a rubber article involves modifying the crosslinking density in one region of the article relative to another region of the article. The modification can be carried out by increasing or decreasing the energy transferred to the first region relative to the energy transferred to the second region during vulcanization. In one implementation, the process is conducted in a mold. Rubber parts described have two or more regions that differ from one another with respect to their crosslinking density.

  • METHODS OF PREPARING A COMPOSITE HAVING ELASTOMER AND FILLER
    Publication number: 20220332016
    Abstract: Disclosed herein are methods of preparing composites from solid elastomer(s) and wet filler(s), as well as products, including composites, vulcanizates, and articles therefrom. The wet filler can have a liquid content of at least 15%. A resulting composite comprises the filler dispersed in the elastomer at a loading of at least 20 phr with a filler yield loss of no more than 10%, wherein the composite has a liquid content of no more than 10% by weight based on total weight of said composite.
