NBR rubber rollers have excellent oil resistance. In a typical NBR structure, trans accounts for about 78%. Due to the cyano group contained in the NBR molecular chain structure, oil resistance (such as resistance to mineral oil, liquid fuel, animal and vegetable oils and solvents) is superior to natural rubber, neoprene and styrene-butadiene rubber. Compared with other rubbers, NBR has a wider range of use temperature, its long-term use temperature is 120 ° C, and NBR has good low temperature resistance, the minimum glass transition temperature can reach -55 ° C.

NBR has good chemical resistance and good processing performance. With the increase of acrylonitrile content in its structure, its relative density increases, the vulcanization speed increases, and the tensile strength performance improves, but the resilience performance decreases, and the cold resistance deteriorates. Because the cyano group in NBR is easy to be polarized by electric field, the dielectric properties are reduced, and it is a semiconductor rubber. NBR can be divided into 5 categories according to the level of ACN content: ultra-high, high, medium-high, medium and low acrylonitrile. Production methods are divided into continuous and batch polymerization methods. The continuous polymerization method is usually used for low-variety and high-volume production with low consumption. The batch polymerization method is suitable for multi-variety and small batch production, and the engineering construction consumption is high.
