1、 Introduction to the applicable temperature range of rubber sealing rings

Rubber sealing ring is a common sealing component widely used in various mechanical equipment, such as automobiles, machine tools, pressure vessels, etc. Rubber sealing rings have good sealing performance, can effectively prevent leakage and pollution, strong adaptability, and long service life. However, the applicable temperature range of rubber seals is limited, and temperatures that are too high or too low can affect their sealing performance.

2、 Applicable temperature range of rubber sealing ring

The applicable temperature range of rubber sealing rings is limited by their material types. Generally speaking, the applicable temperature range of commonly used rubber sealing rings is between -40 ℃ and 120 ℃. Among them, the applicable temperature range of fluororubber sealing rings is between -20 ℃ and 200 ℃. If used in high temperature environments, silicone rubber sealing rings can be used, and their applicable temperature range is between -60 ℃ and 230 ℃.

3、 Characteristics of rubber sealing rings

In addition to the applicable temperature range, there are some characteristics of rubber seals that need to be understood. Firstly, the heat resistance of rubber sealing rings. Generally speaking, the thermal stability of rubber sealing rings is related to their hardness. The higher the hardness, the stronger the thermal stability. The second is the anti-aging performance of the rubber seal ring. The rubber seal ring is easy to age in high temperature and oxidizing environment, which affects its service life. Once again, the corrosion resistance of rubber sealing rings is important. Rubber sealing rings may be susceptible to corrosion from chemicals in the medium, and selecting appropriate materials can reduce the impact of corrosion.

In summary, rubber seals can be safely used within the temperature range of -40 ℃ to 120 ℃, and rubber seals of different materials have different applicable temperature ranges and characteristics. When selecting and using rubber seals, appropriate materials and models should be chosen according to specific circumstances to ensure their effectiveness and safety.The image is from the internet.
