• Advantages and disadvantages of ethylene propylene rubber and nitrile rubber for automobile engine system seals?

    Ethylene-propylene rubber EPDM is made by copolymerization of ethylene and propylene, so it has excellent heat resistance, aging resistance, ozone resistance, and stability, but it cannot be sulfurized. In order to solve this problem, a small amount is introduced into the EP main chain It has the th... read more

  • What are the characteristics and applications of nitrile rubber gaskets?

    1. Characteristics of nitrile rubber gasket: petroleum base oil, hydrocarbon resistance and water resistance increase with the increase of acrylonitrile content, but the low temperature and air permeability will decrease accordingly. It is not suitable for phosphate ester, hydraulic oil and containi... read more

  • What are the basic characteristics of rubber gaskets?

    1. When the rubber gasket is molded, the cohesive force of the elastomer cannot be eliminated due to the large pressure limit. When the molding is released, the extremely unstable shortening often occurs (the shortening rate of the rubber depends on the type of rubber. There are differences), it mus... read more
