The rubber ring seal has good elasticity, low compression, permanent [long] deformation and aging resistance. In addition, different mechanical equipment and sealing media are different, and the rubber material should also have certain special properties. In the hydraulic system, the rubber material is required to have good oil resistance, temperature resistance, and low compression permanent [long] deformation. Therefore, rubber ring sealing rings are widely used in metallurgy, petroleum, automobile, machinery, water conservancy, textile, printing, pipeline, medical, electronic appliances, hardware accessories, construction equipment and other industrial fields.
In addition to the above requirements, the rubber ring sealing ring should also consider the wear resistance and tear resistance of the rubber material. If it is used for rubber ring sealing rings in vacuum environment, the rubber material of the sealing ring is required to have good air tightness, non-volatile and so on. The rubber ring seal for special media requires the volume change and hardness change of the rubber in the medium, and other properties do not change much. In short, the formula design of the rubber ring sealing ring should be comprehensively considered according to the specific working conditions, use temperature, working pressure, medium type and application status.
Therefore, the material of the rubber ring sealing ring has a variety of options, including nitrile rubber, fluororubber, natural rubber, neoprene rubber, silicone rubber, EPDM rubber, etc., among which, from the technical requirements and application of O-ring sealing rings, the amount of rubber consumption [zuì] of nitrile rubber is large, followed by fluororubber, neoprene rubber and silicone rubber, the amount of acrylate rubber and ethylene propylene rubber will be relatively less.
In addition, Guangdong Zhongxiang supports customized rubber ring sealing rings and various silicone rubber products, among which, O-type sealing rings have oil-proof, waterproof, anti-corrosion, sealing gas, anti-leakage sealing rings, as well as high temperature resistance, high pressure resistance, corrosion resistance, ozone resistance, aging resistance, wear resistance and other rubber ring sealing rings; The color of the rubber ring sealing ring can also be made according to the requirements of the drawing.
