Use of precipitated silica containing aluminum, of a precipitated silica and 3 - acryloxy - propyltriethoxysilane in a composition of elastomer (s) isoprene (s))

摘要

The present invention relates to the combined use, in a composition of elastomer (s) comprising an isoprene elastomer, the combination of a precipitated silica containing aluminium, the aluminum content of said precipitated silica is greater than 0,5% by weight, and a precipitated silica as reinforcing inorganic filler, and 3 - acryloxy - propyltriethoxysilane, as coupling agent inorganic filler - elastomer. It also relates to the compositions of elastomer (s) obtained and the articles manufactured from the said compositions.
