Hydrogenated Nitrile Butadiene Rubber (HNBR)

Hydrogenated Nitrile Butadiene Rubber (HNBR) is a high-performance synthetic elastomer derived from the hydrogenation of conventional nitrile rubber (NBR). This process provides enhanced thermal stability, chemical resistance, and mechanical properties, making HNBR ideal for demanding automotive, industrial, and oil & gas applications.

Key Properties:

• Excellent heat, ozone, and oxidative resistance, capable of continuous service up to 150–160°C

• Outstanding oil, fuel, and chemical resistance, including hydrocarbon-based fluids

• Superior tensile strength, abrasion resistance, and compression set

• Good low-temperature flexibility compared to standard NBR

• Wide range of hardness and compound options for specific performance requirements

Common Applications:

• Seals, O-rings, gaskets, and diaphragms in automotive and industrial equipment

• Fuel system components, hoses, and couplings

• Oilfield equipment and downhole seals

• Hydraulic seals and pressure-sensitive applications

• Industrial belts, diaphragms, and vibration-damping components
