Claims4
A cured elastomer composite comprising at least one elastomer, at least one silica-containing particulate filler, at least one coupling agent, and at least one further additive, wherein the elastomer is natural rubber, and the silica-containing filler is present in an amount of from about 40 to 90 phr, and wherein the cured elastomer composite has a T300/T100:tan delta ratio (tan delta measured at 60° C.) of 47 to 70.
An elastomer composite comprising at least one elastomer, at least one silica-containing particulate filler, at least one coupling agent, and at least one further additive, and the silica-containing particulate filler is present in an amount of from about 10 to 90 phr, and wherein the elastomer composite, as produced, has a free antioxidant level of at least 70% by mass of the antioxidant present in the elastomer composite.
