First claim
Opening claim text (preview).
What is claimed is: 1. 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 T 300 /T 100 :tan delta ratio (tan delta measured at 60° C.) of 47 to 70. 2. The cured elastomer composite of claim 1 , wherein said at least one further additive comprises at least one antioxidant. 3. The cured elastomer composite of claim 1 , wherein said silica-containing filler contains 50 wt % or less silica, based on the weight of said silica-containing filler. 4. 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.
