Abstract
A novel elastomeric composition of matter comprises a suitable elastomer, a masterbatch consisting of a silicone compound in an amount of from about 10 to about 50 parts by weight based upon the weight of the elastomer, titanium dioxide, and clay. A process for the preparation of a silicone-containing elastomeric composition of matter is provided and includes the steps of masterbatching a silicone compound, clay and titanium dioxide to form a dispersion, adding the dispersion to the elastomer and thereafter forming and curing a desired product therefrom. The composition is useful in the manufacture of rubber goods such as surgical and medical products which can be single or multi-layered.
