Nitrile (NBR)

Nitrile rubber, also known as NBR (acrylonitrile butadiene rubber), is a type of synthetic rubber copolymer composed of acrylonitrile and butadiene monomers. The proportions of these monomers can vary, leading to nitrile rubbers with different properties. Generally, higher levels of acrylonitrile result in increased oil and chemical resistance but decreased flexibility, while higher levels of butadiene enhance flexibility but reduce oil resistance.

Properties

• Exceptional resistance to oil and fuel
• Good resistance to a wide array of chemicals including acids, bases, and solvents
• Flexibility across a wide range of temperature conditions
• Abrasion resistance
• Moderate resistance to weathering, ozone, and UV radiation

Applications

• Seals, gaskets, and O-rings
• Hoses
• Gloves
• Molded and extruded products across various industries

Industries

• Automotive
• Aerospace
• Oil and gas
• Industrial manufacturing

Overall, nitrile rubber's combination of properties makes it a versatile material suitable for demanding applications were resistance to oils, fuels, and chemicals is critical.
