摘要
A chemically treated carbon black product is provided, which includes a pellet having an agglomerated mass of carbon black aggregates densified in a generally spheroidal form. The carbon black aggregates have polysulfide adsorbed on surfaces thereof. The polysulfide is thereby distributed throughout the pellet. Elastomeric compositions containing the chemically treated carbon black are also provided, and exhibit a reduction in hysteresis and equivalent or better abrasion resistance. A method for manufacturing the treated carbon black product is also disclosed.
