Product Description

Description:HNBR hydrogenated nitrile rubber compound is a semi-finished product of hydrogenated nitrile rubber, which is processed by internal mixer or open mill through reinforcing and filling, adding various processing AIDS, vulcanization active agents and other raw materials. The formula design is customized for the product factory according to different technical requirements. Hydrogenated nitrile rubber is made from Nitrile rubber.The product obtained by hydrogenating and saturating the carbon-carbon double bond in the middle molecular chain is also called highly saturated nitrile rubber. Through vulcanization and crosslinking, obtained with excellent heat resistance, ozone resistance, oil resistance, chemical reagent resistance .

Main applications:
     HNBR hydrogenated nitrile rubber compound is widely used in automobile manufacturing, oil field exploitation, air conditioning, printing and other industries after processing and molding. Sulfur vulcanization system is used for dynamic properties and bonding properties of steel and fiber composites. Peroxide curing systems can be used to improve heat resistance and compression set properties.

Special properties:
    Rapid calendering and extrusion and smooth surface
    The storage stability is good
    And that tear performance is excellent
    Low voltage transformer
    Excellent ozone & weather resistance
    Excellent grease and solvent resistance
    Excellent heat resistance
    Excellent low temperature performance
    Excellent antistatic property
    Excellent medium and high wear resistance
    Excellent mechanical properties, high strength

Curing Condition:
          1) bis-25 (2,5-dimethyl-2,5-di (t-butylperoxy) hexane) peroxide was added together with a
mixture of co- crosslinking agent was vulcanized at 175 ºC@8 min.
          2) carrying out secondary vulcanization at 150ºC@ 4 hours.
