[NG] Rubber bellows expansion joints“die casting machine”

The official website of Shanghai Songjiang shock absorber Group Co., Ltd. introduces to you: [NG] Rubber bellows expansion joints”die casting machine” information. NG Rubber bellows expansion joints product is used for vibration and noise reduction of oil suction pipe of hydraulic system of die casting machine. The following is the introduction of Rubber bellows expansion joints.

[NG] Rubber bellows expansion joints

NG oil resistant Rubber bellows expansion joints is made from butadiene and acrylonitrile by emulsion polymerization. It is mainly produced by low temperature emulsion polymerization. It is a synthetic rubber. It has high oil resistance, high wear resistance, good aging resistance, good heat resistance and strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor electrical performance and low elasticity. Nitrile rubber is mainly used to manufacture oil resistant rubber products, oil transmission pipes of automobile oil tanks, pipes used by excavators, a variety of oil resistant gaskets, gaskets, sleeves, etc. it has become an essential elastic material in automobile, aviation, petroleum, photocopying and other industries. Nitrile rubber is known for its excellent oil resistance. It is a synthetic rubber prepared by copolymerization of butadiene and acrylonitrile. It is a synthetic rubber with good oil resistance (especially alkane oil) and aging resistance. There are five kinds 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 the oil resistance, but the cold resistance decreases accordingly. It can be used in air at 120 ℃ or oil at 150 ℃ for a long time.
