Nitrile Rubber (NBR)
Excellent resistance to oils, fuels, and solvents for industrial applications
View SpecificationsIndustrial Use Nitrile Rubber
Nitrile Rubber (NBR - Nitrile Butadiene Rubber) is a synthetic elastomer renowned for its exceptional resistance to oils, fuels, greases, and solvents. It is the preferred material for applications in contact with hydrocarbons and industrial fluids.
With a Shore A hardness of 65-70, nitrile offers a perfect balance between chemical resistance and mechanical properties, maintaining good flexibility and durability under demanding working conditions.
Superior Chemical Resistance
Nitrile Rubber stands out for its unmatched resistance to:
- Mineral and synthetic oils of all types
- Fuels such as gasoline, diesel, and kerosene
- Industrial greases and lubricants
- Aliphatic solvents and many aromatic ones
- Hydraulic and transmission fluids
This chemical resistance makes it indispensable in automotive, aerospace, petrochemical, and manufacturing industries.
