Method of preparing powdered elastomer compositions

摘要

An improved process is used to prepare encased powdered elastomers which replace slab rubber in injection molding formulations and thereby eliminates the need for milling and high shear mixing. A composition is obtained which is easily blended and is capable of being automatically fed to injection molding machines, and which contains less encasement compound than prior art powdered elastomers having similar nonagglomerating and free-flowing properties.
