Nitrile rubber soft connection, also known as nitrile rubber joint, is a flexible rubber elastic joint, and its main material is nitrile rubber. Nitrile rubber is abbreviated as NBR. It is mainly produced by low-temperature lotion polymerization, with excellent oil resistance. A synthetic rubber obtained by copolymerization of butadiene and acrylonitrile. Nitrile rubber is known for its excellent oil resistance, excellent wear resistance, aging resistance, and airtightness, making it widely used in the rubber industry. There are five types of acrylonitrile content (%) in nitrile rubber, including 42-46, 36-41, 31-35, 25-30, and 18-24. The higher the content of acrylonitrile, the better its oil resistance. It can be used for a long time in air at 120 ℃ or in oil at 150 ℃.
As nitrile rubber also has good water resistance, air tightness and excellent bonding performance, the rubber soft joints processed from it as raw materials are widely used to make various oil resistant rubber products for water supply and drainage, circulating water, HVAC, fire protection, paper making, pharmaceutical, petrochemical, ships, water pumps, compressors, fans and other pipeline systems, such as power plants, water plants, steel plants, water companies Engineering construction, etc.
