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.

Methods of preparing a composite having elastomer and filler

Core particles produced in situ or introduced as preformed core particles are coated with a layer of carbon. Non-carbon as well as some carbon-based core materials can be utilized. The resulting carbon coated particles can find applications in rubber products, for instance as reinforcement for tire components.

Carbon-coated particles

Methods to prepare elastomer compounds are described that include dry mixing at least one additive to an elastomer composite masterbatch at low temperatures over a shortened mixing cycle with reduced energy consumption. The elastomer composite masterbatch is produced in a liquid masterbatch process. The resulting elastomer compounds are further described as well as property improvements that can be achieved.

The invention is directed to processes for increasing the surface area of a carbon black starting material and for forming mesoporous carbon black. The process includes the step of contacting a carbon black starting material having a first BET nitrogen surface area with an oxidant in a fluidized bed under conditions effective to form a carbon black product having a second BET nitrogen surface area greater than the first BET nitrogen surface area. The invention is also directed to carbon black product formed by this process.
