Additional Information

Acrylonitrile butadiene rubber (NBR), also known as nitrile rubber, is a versatile elastomer renowned for its exceptional oil and fuel resistance. This makes it the preferred material for hoses, seals, and gaskets in automotive and industrial applications exposed to oils, fuels, and solvents. NBR also offers good abrasion resistance, contributing to its use in wear-resistant components and footwear soles.

NBR exhibits good heat resistance, allowing it to perform reliably in moderate-temperature environments. Additionally, it possesses good flexibility and resilience, ensuring proper sealing and functionality in demanding applications. NBR offers water resistance, further expanding its use in various environments.

However, NBR can be susceptible to ozone degradation and requires specific considerations for processing due to its higher viscosity compared to some other elastomers.
