HNBR: Exploring the Benefits and Applications

HNBR (Hydrogenated Nitrile Butadiene Rubber) is a specialized elastomer material that offers excellent resistance to heat, ozone, and chemicals. It is widely used in the automotive and oil and gas industries due to its excellent mechanical properties and resistance to high-temperature and harsh chemical environments. HNBR is commonly used to make O-rings, gaskets, custom rubber parts, etc. In this blog, we will take a closer look at HNBR rubber and its various applications.

What is HNBR Rubber?

HNBR rubber is a synthetic elastomer material that is created by hydrogenating Nitrile Butadiene Rubber (NBR).

HNBR is formed by subjecting Nitrile rubber to a hydrogenation process. The hydrogenation process increases the saturation of the polymer chain, resulting in a compound that demonstrates increased temperature resistance and better compatibility with ozone, and many fuels & chemicals. HNBR rubber also offers excellent mechanical properties and abrasion resistance. Hydrogenated Nitrile also offers higher strength and reduced degradation at high temperatures compared to conventional Nitrile. These properties make HNBR popular in the oil and gas industry, as well as many applications in the chemical industry. Specific physical and chemical resistances vary by compound formulation.

Common names include: HNBR (Hydrogenated acrylonitrile butadiene rubber), Hydrogenated Nitrile Trade Names: Therban®, Zetpol®

How Does HNBR Rubber Work?

HNBR rubber offers excellent resistance to high-temperature environments due to its highly saturated polymer chains. The material is also highly resistant to ozone and chemicals, making it a popular choice for use in the automotive and oil and gas industries.

HNBR rubber has good tensile strength, elongation, and compression set, making it an ideal material for manufacturing seals, gaskets, and other components that require excellent mechanical properties and chemical resistance. If you would like to learn more, see our HNBR page.
