Nitrile Butadiene Rubber (NBR)
Nitrile Butadience Rubber (NBR), or Buna-N, is a copolymer of butadiene and acrylonitrile.
Features:
– NBR is a general purpose oil resistant polymer, with good solvent, oil, water and hydraulic fluid resistance. It also has good elongation properties and demonstrates adequate resilience, tensile and compression set.
– NBR material properties make it an excellent solution for sealing applications.
Application:
- Gaskets
- O-rings
- Nitrile roll covers
- Hydraulic hoses
- Conveyer belts
- Nitrile tubing
