ELASTOMER COMPOSITE BLENDS, METHOD AND APPARATUS FOR PRODUCING SAME

Document Type and Number:

WIPO Patent Application WO/2011/034587

Kind Code:

A3

Abstract:

A wet mix elastomer composite comprising carbon black dispersed in an elastomer including a blend of a natural rubber and styrene-butadiene rubber. When the wet mix elastomer composite is processed with CTV Method 1, the vulcanized wet mix elastomer composite exhibits a resistivity that A) has a natural logarithm satisfying the equation 1n(resistivity) ≥ -0.1(loading) + x, where x is 14, or B) is at least 2.9 times greater than the resistivity of a vulcanized dry mix elastomer composite having the same composition and prepared using Comparative CTV Method 1.
