Abstract:
      The properties of different grades of hydrogenated nitrile rubber(HNBR) compounds and vulcanizates were characterized by rubber processing analyzer(RPA)，and compared with other testing instruments. The results showed that the curing rate and filler dispersion of HNBR compound and mechanical properties of HNBR vulcanizate increased with the increase of the Mooney viscosity of HNBR. The aging resistance of HNBR vulcanizate increased with the increase of the hydrogenation degree of HNBR. The loss factor and glass transition temperature of HNBR vulcanizate increased with the increase of the acrylonitrile content of HNBR. RPA could be used to obtain the test results that usually required multiple instruments，such as rotorless vulcanizer，universal material testing machine，scanning electron microscope and dynamic mechanical analyzer. Therefore，RPA could be used to conveniently regulate the compound formulation of HNBR with different grades to obtain the expected results.
