Tips: Advantages of NBR
- Nitrile butadiene rubber has good heat resistance, and its heat resistance is better than natural rubber and styrene butadiene rubber.
- Rubber is endowed with better physical and mechanical properties and wear resistance by reinforcement.
- The antistatic property is excellent, and the plasticizing effect is better with polar lipids.
- Good compatibility with polar substances, such as PVC, alkyd resin, nylon.
