Product type
Nitrile Butadiene Rubber (NBR) is a synthetic rubber copolymer made from the polymerization of acrylonitrile and butadiene. It is known for its excellent resistance to oil, fuel, and other chemicals, making it a popular choice in various industrial applications. NBR is typically produced in various grades, which can be tailored to meet specific performance requirements.
| Hardness | Shore A 40 to 90 |
| Temperature range | -40°C to 100°C |
| Acrylonitrile content | 18% to 50% |
| Tensile strength | 10 to 30 MPa |
| Elongation at break | 300% to 600% |
When selecting Nitrile Butadiene Rubber, consider the specific application requirements such as hardness, temperature resistance, and chemical exposure. Buyers should specify the desired acrylonitrile content to ensure optimal performance for oil and fuel resistance. Additionally, certifications and compliance with industry standards may be important depending on the application.
