CR232 is characterized by excellent storage stability,
process ability and safety property , and its products have sunlight resistance , oil resistance , chemical reagent resistance and combustion retardancy as well as heat resistance and less compression deformation. But its vulcanization rate is slow and should be solved by adjusting the vulcanization system.
