Abstract
A highly reversion resistant polyisoprene elastomer composition vulcanized with a low sulfur content is described and used in paper feed belts. The polyisoprene rubber compositions are particularly useful in the paper feed belts used to feed and transport paper in xerographic machines and paper sorting machines. The low-sulfur vulcanizate of isoprene provides high resistance to physical degradation due to dynamic mechanical stress under operating conditions.
