What is NBR rubber

Nitrile Butadiene Rubber (NBR) is a kind of synthetic Rubber, which is a copolymer polymerized from acrylonitrile and Butadiene monomer. It has such advantages as excellent oil resistance (especially alkane oil), high wear resistance, good air tightness, good heat resistance, strong adhesion and good aging resistance.

Disadvantage is low temperature resistance, poor ozone resistance, poor insulation, slightly lower elasticity, should not be used as insulation materials.

Germany first began commercial production in 1937.

Although the chemical and physical properties of NBR vary with the amount of cyanogen in the polymer, NBR remains resistant to oil, gasoline and other solvents.

The higher the cyanide content in the polymer, the stronger the corrosion resistance and the worse the elasticity.

Nitrile butadiene rubber is used in the manufacture of oil hose, flame retardant conveyor belt.

Secondly, it is used for sealing devices in automobile industry, as well as oil-resistant gaskets, gaskets, sleeves, flexible packaging, soft rubber tubes, printing and dyeing cots, cable rubber materials, and protective gloves in nuclear industry.

Nitrile rubber has a strong ability to adapt to temperature, can be in - 40 to 108 ° C temperature range to work properly, this feature makes the nitrile rubber is widely used in the aviation industry.

Nitrile rubber can also be cast into a variety of products.

The high elasticity of NBR makes it the raw material for the manufacture of disposable laboratory gloves.

Nitrile rubber is also more resistant to oil and acid corrosion than natural rubber.

Although lower in elasticity and strength than nr, NBR is several times more resistant to corrosion than nr.
