Hydrogenated nitrile butadiene rubber (HNBR) is a high-performance elastomer known for its exceptional resistance to heat, oil, and chemicals. HNBR rubber exhibits
- Strong Wear Performance
- Superior Chemical Resistance
- Weather & UV Resistance
- High-Temperature Resistance
The hydrogenation process enhances stability and durability, making it suitable for demanding applications in automotive, aerospace, and oil industries. HNBR has also been evaluated as a cost-effective alternative to FKM (Viton™) for select high performance applications (see our article on FKM vs HNBR to learn more).
