Nbr And Ethylene Blend

Abstract: A rubber composition having a polymer blend of nitrile and ethylene terpolymers, particularly acrylonitrile-butadiene copolymer (NBR) and ethylene polymers. The composition has NBR as 30-50 wt.-% of the total composition. In some embodiments, the ethylene polymer is EPDM rubber, an ethylene acrylic elastomer, or a chlorinated polyethylene. 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 reinforcing material such as carbon black.
