Nitrile Blend Rubber (NBR)

Nitrile rubber, often referred to as NBR (acrylonitrile-butadiene rubber), is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. Nitrile rubber blends are created by combining nitrile rubber with other materials to enhance certain properties or meet specific application requirements. The properties of nitrile blend rubber can vary depending on the specific composition and the intended use. Some general features and benefits associated with nitrile blend rubber are as follows:

Features and Benefits

Oil Resistance

Nitrile rubber, in general, has excellent resistance to oils and fuels. Nitrile blends often retain this property, making them suitable for applications where exposure to oil or fuel is a concern.

Temperature Resistance

Nitrile rubber typically has good resistance to moderate temperatures. The temperature resistance of nitrile blends can be influenced by the specific additives or fillers used in the blend.

Chemical Resistance

Nitrile rubber provides resistance to a variety of chemicals. However, the chemical resistance of nitrile blend rubber depends on the specific chemicals involved and the blend composition.

Flexibility and Durability

Nitrile rubber is known for its flexibility and durability, and these characteristics are often maintained in nitrile blend rubber products.

Tensile Strength

Nitrile blends generally exhibit good tensile strength, making them suitable for applications where strength and resilience are important.

Compression Set Resistance

Nitrile rubber blends can resist permanent deformation under compressive stress, known as compression set. This property is important in applications where the material is subjected to pressure.

Weather Resistance

While nitrile rubber is not as resistant to ozone and weathering as some other elastomers, the addition of certain materials in a blend can improve its weather resistance.

Flame Resistance

Depending on the specific formulation, nitrile blends may have varying degrees of flame resistance.

Low-Temperature Flexibility

Nitrile rubber typically maintains good flexibility at low temperatures, and this property may be retained in nitrile blend rubber.
