HNBR is also known as Highly Saturated Nitrile or HSN. It’s a special class of nitrile rubber that has been hydrogenated to increase the saturation of the butadiene segment of the carbon polymer backbone.
The compound withstands both hot and cold temperatures and is renowned for its physical toughness. Additional characteristics include:
High mechanical strength
Excellent heat and oxidation stability
Resistance to modern oils, fuels, and coolants
Improved wear resistance
Temperature range from -60 degrees Celsius to 160 degrees Celsius
