Halogenated Polyethylene And Ethylene Polymer Blends

Abstract

A rubber composition having a blend of ethylene polymers, particularly halogenated and non-halogenated ethylene polymer. The composition has the halogenated ethylene as 25-50 wt.-% of the total composition. In some embodiments, the non-halogenated ethylene polymer is an ethylene acrylic elastomer. The composition can include an organic peroxide or other accelerator. The rubber composition is useful for synchronous belts having moderate to high temperature resistance, good fuel resistance, flexibility down to −40° C. and high structural integrity. Additionally, the rubber composition allows reduction in the amount of fossil fuel derived reinforcing materials such as carbon black.
