NBR has excellent oil resistance. Butadiene monomers can be copolymerized into three different chain structures: cis, trans, and 1,2-carbonyl. In typical NBR structure, trans-formation accounts for about 78%. The manufacturer of NBR rubber powder believes that the oil resistance (such as resistance to mineral oil, liquid fuel, animal and vegetable oil and solvent) is superior to natural rubber, neoprene and styrene-butadiene rubber due to the presence of cyanide in the molecular chain structure of NBR. 

Compared with other rubbers, NBR has a wider range of service temperature, and its long-term service temperature is 120oC. At the same time, NBR has good low temperature resistance, and its low glass transition temperature can reach - 55oC.

NBR has good chemical stability and good processing performance. With the increase of the relative density of acrylonitrile content in its structure, the curing rate is accelerated, and the tensile strength is improved, but the resilience is decreased, and the cold resistance is poor. Because the cyano group in NBR is easy to be electrified, the dielectric property of NBR is reduced, which is semiconductor rubber.

NBR can be divided into five categories according to the content of ACN: ultra-high, high, medium-high, medium-low acrylonitrile. 

There are two production methods: 

continuous polymerization and batch polymerization. The continuous polymerization method is usually used for small variety and large yield production with low consumption. The batch polymerization method is applicable to multiple varieties and small batch production. The number of polymerization tags is small and the engineering construction consumption is high. So far, there is no trend of mutual substitution.
