(1) The code name of nitrile butadiene rubber: NBR nitrile butadiene rubber is a synthetic rubber made by copolymerizing butadiene and acrylonitrile. It is a synthetic rubber with good oil resistance (especially nitrile rubber alkane oil) and good aging resistance.

(2) The acrylonitrile content (%) in the nitrile rubber gasket has five types: 42-46, 36-41, 31-35, 25-30, 18-24. The more acrylonitrile content, the better the oil resistance, but the cold resistance decreases accordingly. It can be used for a long time in the air at 120°C or in oil at 150°C. In addition, nitrile rubber gaskets also have good water resistance, air tightness and excellent bonding properties. Widely used in the manufacture of various oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, casings, flexible packaging, flexible hoses, printing and dyeing rubber rollers, cable rubber materials, etc., becoming indispensable in industries such as automobiles, aviation, petroleum, and copying The elastic material.

(3) Nitrile rubber is mainly used to make oil-resistant products, such as oil-resistant pipes, tapes, rubber diaphragms, and large oil sacs. It is often used to make various oil-resistant molded products, such as O-rings, oil seals, cups, diaphragms, and valves. , Bellows, etc., are also used to make rubber sheets and wear-resistant parts. The service life of oil-resistant rubber joints is more than three years. Our factory provides a one-year warranty for rubber joints used on hydraulic oil pipelines. Hope it helps you
