Overview sealing rings are a must in industrial production. Different product types and materials have different characteristics and functions. sealing rings are mainly used in various equipment. Due to different materials, they can The temperature and pressure it can withstand are different, and the liquid and gas environments it can be in are also different, and the rubber sealing ring has dynamic and static points, which play a sealing role in different states. 1 Nitrile rubber sealing ring The biggest advantage of Nitrile rubber is its oil resistance and aromatic solvent properties, but the disadvantage is that it is not resistant to ketones, esters and chlorinated substances such as medium, so the sealing required for oil resistance The product is best to choose nitrile rubber material. 2. The advantage of this rubber seals material is that it can resist the invasion of some oils, solvents, and chemical media. The disadvantage is just the opposite of nitrile rubber, which is not resistant to aromatic oils, but it is resistant to all-weather aging and ozone aging. It has excellent performance, so neoprene rubber is generally used in production to make door and window seals, diaphragms and vacuum sealing products. 3 Chlorine rubber sealing ring The most prominent feature is high temperature resistance, the working environment range is between -30 ℃ to +250 ℃, and this rubber has good resistance to strong oxidants, oil, acid and alkali. This rubber is generally used in high temperature and high pressure environments, and is very suitable for oily working environments. Chlorine rubber is widely used in petroleum, chemical and aerospace sectors. 4 Silicone rubber sealing ring The outstanding advantage of silicone is that it has good low temperature resistance, and it can still maintain good elasticity in the working environment between -70 ° C and +250 ° C. It is resistant to weathering and ozone. It has good aging properties, can be used as a gasket for sealing in thermal machinery, and finally can be used in food and medical applications due to the non-toxicity of this rubber.
