ELASTOMERIC COMPOSITION USEFUL AS TIRE SHOES.

摘要

The present invention describes a sulfur-vulcanizable elastomeric composition, useful to prepare tire shoes, comprising: a) 100 parts of elastomeric mixture comprising from 20 to 100 percent by weight of an elastomer which is derived from polymerization of a monovinylarene with a conjugated diene, preferably a styrene-butadiene copolymer, a complement to 100 is selected from natural rubber, polybutadiene and another diolefinic elastomers; b) from 10 to 150 parts of silica by 100 parts of (a); c) from 0 to 150 parts of lampblack by 100 parts of (a); characterized in that the elastomeric mixture (a) has an epoxidation degree of 0.7 to 8.0 percent.
