Nitrile Rubber

Nitrile rubber, also known as NBR (Nitrile Butadiene Rubber), is a synthetic rubber with excellent oil and fuel resistance, making it a preferred material for a wide range of applications. Here are typical specifications for nitrile rubber:

1. Polymer Type:

• Nitrile rubber is a copolymer of butadiene and acrylonitrile. Specifications include details about the specific composition and the ratio of these monomers.

1. Physical Properties:

• Nitrile rubber is known for its excellent physical properties, including high tensile strength, good flexibility, and resistance to abrasion. Specifications provide details on hardness (measured on the Shore Durometer scale), tensile strength, elongation at break, tear resistance, and modulus.

1. Oil and Fuel Resistance:

• Nitrile rubber excels in resisting oils, fuels, and greases, making it suitable for applications in contact with petroleum-based fluids. Specifications may include information on the types of oils and fuels it can resist.

1. Temperature Range:

• Nitrile rubber typically has a moderate temperature resistance range. Specifications outline the material's effective temperature range, including low-temperature flexibility and high-temperature stability.

1. Chemical Resistance:

• While nitrile rubber is resistant to oils and some chemicals, specifications may provide details on its performance against specific chemicals or substances.

1. Weather Resistance:

• Nitrile rubber may have limited resistance to weathering and ozone exposure compared to other rubbers. Specifications highlight its ability to withstand outdoor conditions.

1. Flame Resistance:

• Nitrile rubber is inherently resistant to flames, but specifications may provide details on its self-extinguishing properties and performance in the presence of an open flame.

1. Electrical Insulation Properties:

• Specifications may detail the electrical insulation properties of nitrile rubber, including dielectric strength, volume resistivity, and other relevant characteristics.

1. Compression Set:

• Specifications include information about the compression set, which is the ability of the rubber to return to its original shape after being compressed.

1. Color and Appearance:

• Nitrile rubber is typically black, but specifications may include information on the standard color and appearance. Colored variations are also available.

1. Fabric Reinforcement:

• Some nitrile rubber formulations may include fabric reinforcement for added strength. Specifications may specify the type, orientation, and density of fabric reinforcement if applicable.

1. Industry Standards:

• Compliance with industry standards, such as ASTM D2000, may be mentioned in the specifications to ensure that the nitrile rubber meets recognized quality and performance benchmarks.

It's important to refer to specific product data sheets provided by manufacturers for detailed information about the nitrile rubber's properties, formulation, and intended use. Specifications may vary depending on the specific grade and application requirements.
