NBR has excellent oil resistance. The trans form accounts for about 78% of the typical NBR structures. Because the molecular chain structure of NBR contains cyano group, its oil resistance (such as resistance to mineral oil, liquid fuel, animal and vegetable oils and solvents) is superior to that of natural rubber, neoprene and styrene butadiene rubber. Compared with other rubbers, NBR has a wider range of service temperature. Its long-term service temperature is 120 ℃. At the same time, NBR has good low temperature resistance, and the minimum glass transition temperature can reach - 55 ℃.

NBR has good chemical resistance and processing property. With the increase of acrylonitrile content in its structure, its relative density, vulcanization speed and tensile strength are improved, but its resilience is reduced and its cold resistance is poor. Because the cyano group in NBR is easy to be polarized by electric field, the dielectric property is reduced, and it is semiconductor rubber. NBR can be divided into five categories according to ACN content: ultra-high, high, medium high and medium low acrylonitrile. There are two production methods: continuous polymerization and intermittent polymerization. Continuous polymerization is usually used for production of few varieties and large yield, with low consumption. Intermittent polymerization method is applicable to multiple varieties and small batch production, and the project construction consumption is high.

Although nitrile rubber has excellent physical and mechanical properties and processing properties, its long-term use performance in acidic gasoline and high temperature (150 ℃) environment is not as good as fluororubber and acrylate rubber. Therefore, hydrogenated nitrile rubber (HNBR) with excellent performance has been developed. In addition, nitrile rubber with super cold resistance and high purity and carboxyl nitrile rubber (XNBR) have also been developed.
