(Nitrile Rubber) is made by the co-polymerization of acrylonitrile and butadiene, acrylonitrile content from 18% to 50%. Acrylonitrile content is higher, resistance to petrochemical oil hydrocarbon fuel the better, but the low temperature performance is poor, general operating temperature range is -25 ~ 100 ℃. NBR is one of the most commonly used rubber seals and O-rings.

Advantages:

1). good resistance to oil, water, solvent and high pressure oil properties;

2). good compression resistance;

3). good abrasion-resistant characteristic;

4). good elongation force;

Disadvantages:

  not suitable for polar solvents, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform for the system.

Applications:

For the fuel tank, oil tank and hydraulic oil in the petroleum, gas, water, oil, lubricants and other flow-based diester medium for use in rubber parts, especially the sealing parts can be said is the most widely used and lowest cost rubber seals.
