Nitrile rubber is made from butadiene and acrylonitrile through emulsion polymerization. Nitrile rubber is mainly produced by low-temperature emulsion polymerization.
Nitrile rubber has better heat resistance. Its heat resistance is better than natural rubber, butadiene rubber and styrene-butadiene rubber. The long-term use temperature can reach 100oC, and it can be used for 40 days at 120 ℃.
① Ozone resistance is worse than CR and better than NR
② Give the rubber good physical and mechanical properties and wear resistance through reinforcement
③ When the content of acrylonitrile and nitrile rubber is 39%, the air tightness is equivalent to that of IIR rubber, and the air tightness is better.
④ General low temperature flexibility
⑤ Excellent antistatic performance
⑥ The plasticizing effect of polar lipids is better
⑦Good compatibility with polar substances (such as PVC, acid resin, nylon)
⑧ Poor composition, low self-adhesion, and large heat generation during mixing
NBR is widely used in the manufacture of various oil-resistant rubber products, such as O-rings, loops, hoses and fuel tank linings, printing cylinders, tank linings, insulated floor panels, oil-resistant soles, hard rubber parts, and fabric coating , Pipe thread protective layer, pump impeller, wire cover, adhesive, film for food packaging, rubber gloves and other fields.
