Application: 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 ℃@8 min.

2) carrying out secondary vulcanization at 150℃@ 4 hours.
