High-pressure equipment such as pressure cookers have strict requirements in terms of sealing, and the choice of sealing materials is very critical, so what is the general material of high-pressure sealing rings? Let's find out together.

First, high-pressure sealing ring is generally what material is more commonly used is fluoroelastomer material, this sealing material in high temperature resistance is excellent, even in the temperature of 200 degrees, can also be used normally, and for oil, acid and alkali substances also have good performance, can not only be used in pressure cookers, but also in petroleum, chemical, aerospace and other fields are also very commonly used. Second, what are the sealing materials 1, silicone rubber silicone rubber weather resistance is very good, in the environment as low as minus 70 degrees can also maintain the use effect, in the temperature up to 260 degrees can also have a good use effect, at the same time its service life is relatively long, not easy to appear aging problems, will not be affected by ozone and so on, so suitable for thermomechanical sealing gasket, and it is non-toxic, can make medical rubber products.

2. The sealing ring made of nitrile rubber has good oil resistance and is also more resistant to aromatic solvents, but it should be noted that it cannot be used in environments containing ketones, esters, chlorination and other media.

3, neoprene it is relatively resistant to oil, solvent, chemical medium and other aspects, but it should be noted that it cannot be used in aromatic oil substances, generally used in door and window sealing.

4. Ternary ethylene propylene in door and window seals and car seals, most of them will choose EPDM material to make, it performs well in temperature resistance, weather aging resistance, ozone aging resistance, etc.

5. PTFE is

usually made into PTFE composite gasket for use, which performs well in corrosion resistance and high temperature resistance, and is non-toxic, and can also be well used in the food field.
