Nitrile rubber is a butadiene and acrylonitrile copolymer, both hot- and cold-polymerized polymerized types are available. All having a non-staining antioxidant. NBR is ideal for applications that require excellent oil and fuel resistance.
It presents chemical resistance to organic substances such as aliphatic oils and nonpolar solvents. Increasing the acrylonitrile content, increases its oil, fuel and solvent resistance, reducing the acrylonitrile content, increases low temperature resilience and flexibility.
