Material Introduction

1. Characteristic:

   HNBR (Hydrogenated Nitrile Butadiene Rubber) Rubber is a highly saturated elastomer obtained by special hydrotreating of nitrile rubber. It has good oil resistance(good resistance to fuel oil, lubrication oil, aromatic solvent), and due to its highly saturated structure, it has good heat resistance and excellent chemical resistance(such as freon, acid, alkali, etc.). It also has excellent ozone resistance, high compression set resistance; It's a high strength, high tear performance and excellent wear resistance. Its heat and radiation resistance is better than silicone rubber, fluoro rubber (FKM).

2. Temperature:

   -20 ℃ ~ 150 ℃, some special HNBR rubber could be used up to 180 ℃, and the lowest temperature could be -55 ℃ for short time.

3. Color:
