Project details

HNBR and VITON are two different sealing materials, and the following are some of their differences:

Composition: HNBR is a product obtained by hydrogenation saturation of carbon carbon double bonds on the molecular chain of nitrile rubber, while VITON is a fluorinated rubber.

Performance: HNBR has a highly saturated structure, which gives it good heat resistance, chemical corrosion resistance, ozone resistance, and high resistance to compression permanent deformation. At the same time, HNBR also has characteristics such as high strength, high tear resistance, and excellent wear resistance, making it one of the most excellent rubbers in terms of comprehensive performance. VITON, on the other hand, has excellent chemical corrosion resistance and high-temperature resistance.

Application field: HNBR seals can be used in various sealing and waterproof situations, such as the automotive industry, oil fields, printing, and many other fields. VITON seals are widely used in high-temperature and chemically corrosive environments, such as aerospace, petrochemical, and other fields.

Overall, HNBR and VITON are two different sealing materials that differ in composition, performance, and application areas. The choice of material depends on the specific usage needs and environmental conditions.
