Abstract:
The invention concerns a tire comprising a rubber composition based on at least an elastomer composite prepared by a method comprising: feeding a continuous flow of a first fluid comprising a first elastomer latex to a mixing zone of a coagulum reactor; feeding a continuous flow of a second fluid comprising a second elastomer latex to the mixing zone; feeding a continuous flow of a third fluid comprising a particulate filler slurry to the mixing zone; allowing the first elastomer latex and the second elastomer latex to coagulate with the particulate filler; and discharging a flow of elastomer composite from a discharge end of the coagulum reactor.
Abstract:
The invention provides an aqueous dispersion comprising fumed silica particles, colloidal silica particles, and water. The fumed silica particles have a BET surface area of about 70 to about 140 m /g, and the colloidal silica particles have a BET surface area of about 110 to about 150 m /g. Also, the total amount of silica in the dispersion is about 35% to about 60% by weight, and the fumed silica particles comprise about 25% to about 80% by weight of the total amount of silica in the dispersion. The invention also provides a coating composition and a recording medium incorporating the inventive dispersion.

Abstract:
PROBLEM TO BE SOLVED: To provide a vulcanized elastomer composite.SOLUTION: A vulcanized wet mix elastomer composite includes at least one carbon black having a CDBP value of at least about 65 mL/100 g, for exampleThe vulcanized wet mix elastomer composite exhibits a ratio of T300 to T100 that is 17% higher than the same ratio for a vulcanized dry mix elastomer composite having the same composition. A vulcanized elastomer composite exhibits a ratio of T300 to T100 of at least 5.5 and includes particulate filler dispersed in elastomer, wherein the particulate filler includes at least about 40 phr of at least one carbon black having an STSA value from 165 to 205 m/g and having a CDBP value from about 85 to 110 mL/100 g. The invention is a wet mix elastomer composite consisting essentially of carbon black dispersed in natural rubber. When the wet mix elastomer composite is processed according to CTV method A, the resulting vulcanized wet mix elastomer composite exhibits a resistivity having a natural logarithm that is at least 10% higher than that for a crosslinked dry mix elastomer composite having the same composition and prepared using CTV comparative method A.
