Nitrile rubber (NBR) is a copolymer of butadiene and acrylonitrile. The characteristic is its excellent resistance to gasoline and fatty hydrocarbon oils, second only to polysulfide rubber, acrylic ester, and fluororubber, and superior to other general-purpose rubbers. Good heat resistance, good air tightness, wear resistance, water resistance, and strong adhesion. The disadvantages are poor cold and ozone resistance, low strength and elasticity, poor acid resistance, poor electrical insulation, and poor resistance to polar solvents. Temperature range for use: approximately -30 ℃ to+100 ℃. Nitrile rubber O-rings are mainly used to manufacture various oil resistant products, such as rubber hoses, sealing products, etc. Generally, ordinary oil seals are nitrile rubber seals, which are widely used for their good oil resistance and economy. Our factory's skeleton oil seals are made of high-quality nitrile rubber, which is of high quality and low price. Welcome to call us anytime.
