Material analysis of rubber sealing rings used for installation on various mechanical equipment, under specified temperature and pressure, as well as different liquids and gases, in static or moving states for sealing purposes
1. Fluorine rubber: It has high temperature resistance and can be used in environments between -30 ℃ and+250 ℃. It is resistant to strong oxidants, oil, and acid and alkali. Usually used in high-temperature, high vacuum, and high-pressure environments, suitable for oily environments. Due to its various excellent properties, fluororubber is widely used in sectors such as petroleum, chemical, aviation, and aerospace.
2.Silicone rubber: It has outstanding high and low temperature resistance, maintains good elasticity in the temperature range of -70 ℃ -+260 ℃, and has advantages such as ozone resistance and weather aging resistance. It is suitable as a sealing gasket in thermal machinery. Because it has no toxicity, it can be used to make thermal insulation, insulating products and medical rubber products.
3. Nitrile rubber: It has excellent oil resistance and aromatic solvent resistance, but is not resistant to ketone, ester, chlorination and other media, so oil resistant sealing products are mainly Nitrile rubber.
4. Neoprene: It has good oil resistance, solvent resistance, chemical medium resistance and other properties, but is not resistant to aromatic oil. It is characterized by excellent weather aging and ozone aging resistance. In production, Neoprene is usually used to make door and window sealing strips, diaphragms and general vacuum sealing products;
5. EPDM: It has good temperature resistance, weather resistance, and ozone aging performance, and is usually most widely used in door and window sealing strips and the automotive industry.
6. Polytetrafluoroethylene composite gasket is a new type of sealing material composed of polytetrafluoroethylene and high-quality complete rubber using a special production process. It combines the excellent characteristics of polytetrafluoroethylene and rubber, making the product not only excellent corrosion resistance, but also high-temperature resistance, non-toxic, adhesive resistance, and good elasticity and sealing.
