Products Description
In order to meet the increasing demands for environmental protection, many additives are now found in automotive fuels, such as methanol, ethanol, methyl tert-butyl ether, amine corrosion inhibitors, and anti-wear agents. As a result, rubber components that come into contact with fuels now require higher performance levels. Both HNBR and fluoro rubber exhibit excellent resistance to fuel oil, corrosive media, and low permeability. Compared with fluoro rubber, HNBR has higher tensile strength, better resistance to chemical corrosion, and stronger cold resistance capabilities.

hNBR Advantages
1
Flame and oil resistance
2
Corrosion resistance
3
low temperature resistance
4
High tensile strength
In the manufacturing field of automotive sealing products, HNBR and fluoro rubber can be used to achieve a good balance between fuel oil resistance and low temperature resistance, with HNBR exhibiting superior comprehensive performance over fluoro rubber. This is why HNBR are becoming increasingly popular materials for sealing systems, gaskets, and other related applications in the automotive industry.
HNBR and fluoro ruber are both resistant to high temperatures and corrosive media. HNBR's higher tensile strength, superior resistance to chemical and corrosive media, and greater cold resistance make it ideal for fuel systems, as it remains highly efficient even when exposed to a wide range of fuels and lubricating oils.
HNBR development
Hydrogenated nitrile butadiene rubber (HNBR) has excellent properties and has become a key component in a variety of automotive systems and products.
