Abstract:
An elastomeric compound comprising an elastomer and an aggregate comprising a carbon phase and a silicon-containing species phase, wherein said aggregate imparts to the elastomer poorer abrasion resistance, comparable or higher loss tangent at low temperature and a lower loss tangent at high temperature, compared to an untreated carbon black, and wherein said elastomer is: an oil-extended derivative of one or more elastomers selected from styrene-butadiene rubber, natural rubber, polybutadiene, and polyisoprene; or a co-polymer of a conjugated diene and an ethylenic group-containing monomer, wherein said monomer comprises one or more monomer selected from styrene, methylstyrene, chlorostyrene, acrylonitrile, 2-vinyl-pyridine, 5-methyl 2-vinyl pyridine, 5-ethyl-2-vinyl-pyridine, 2-methyl-5-vinyl pyridine, alkyl-substituted acrylates, vinyl ketone, methyl isopropenyl ketone, methyl vinyl ether, alphamethylene carboxylic acids and the esters and amides thereof.
