What are the thermal stability and corrosion resistance of the sealing ring?

The sealing ring is an important component used to fill and close the gap between equipment to prevent liquid or gas leakage. The thermal stability and corrosion resistance of the sealing ring are one of its key characteristics in industrial applications. The following sealing ring manufacturers will introduce the characteristics of the sealing ring in detail from the two aspects of thermal stability and corrosion resistance.

First of all, the thermal stability of the sealing ring is crucial for its application in high temperature environments. Under high temperatures, general rubber sealing rings tend to soften, swell or lose elasticity, making the sealing effect worse, resulting in leakage. In order to improve the thermal stability of the sealing ring, sealing rings made of high-temperature materials such as high-temperature resistant fluororubber (FKM), polytetrafluoroethylene (PTFE) or silicone are usually used. These materials have a high heat resistance temperature, can maintain sealing performance in high temperature environments, and have good oxidation resistance and aging resistance. Therefore, choosing sealing ring materials suitable for high temperature environments is crucial to ensure the safe and reliable operation of equipment.

Secondly, the corrosion resistance of the sealing ring is crucial to its application in the fields of chemical industry, medicine, food, etc. In some special working environments, such as media with strong acid and alkali corrosion, traditional rubber sealing rings are easily damaged by corrosion, resulting in leakage and equipment damage. Therefore, in these special environments, it is necessary to select sealing ring materials with good corrosion resistance, such as fluororubber, chloroprene rubber, polyurethane, etc. These materials have good chemical corrosion resistance, can resist the erosion of media such as acid and alkali, maintain stable sealing performance, and ensure the safe operation of the equipment.

In general, the thermal stability and corrosion resistance of the sealing ring play a vital role in its use in various industrial applications. Selecting suitable materials and properly installing and maintaining the sealing ring can increase its service life in high temperature and corrosive environments, and ensure the safe and reliable operation of the equipment. Therefore, when selecting a sealing ring, in addition to considering its sealing performance, attention should also be paid to its thermal stability and corrosion resistance to ensure the normal operation of the equipment and the stable improvement of production efficiency.
