China levies anti-dumping duty on Japanese and Korean nitrile butadiene rubber

Acrylonitrile butadiene rubber is made from butadiene and acrylonitrile by emulsion polymerization. Because of its excellent oil resistance, wear resistance, heat resistance and tightness, it is widely used to produce various kinds of oil resistant products, such as O ring, oil seal, hose, hose, gasket, cots, soles, conveyor belts, etc. The export tariff code is 40025910 and 40025990. NBR is mainly produced by low temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. Its shortcomings are poor low temperature resistance, poor ozone resistance, poor insulation performance and slightly low elasticity. NBR is mainly used in the manufacture of oil-resistant rubber products.
