Sealing rings mainly play a role in dust and oil isolation in applications. There are also many sealing media, mainly oil. Therefore, the performance of sealing rings directly affects the performance of other equipment, and the material is the first to determine the performance of sealing rings.

1. Mechanical motion speed. The material of the sealing element has different adaptability to mechanical motion speed. Some ordinary materials cannot adapt to high-speed mechanical operation. Therefore, when choosing the material of the sealing ring, it is necessary to choose a high-end one in order to use high-speed operation.

2. Pressure. The material of the sealing ring is also very sensitive to the working pressure. Different materials can withstand different pressures. If the medium is oil, it can withstand less pressure. If the pressure exceeds the material's bearing range, it will reduce the service life of the sealing ring. You can choose according to the recommendations of the sealing ring manufacturer.

3. Media compatibility. This plays a very important role in the selection of sealing ring materials. Some sealing ring materials may come into direct contact with the medium. If the compatibility between the two is poor, it will inevitably cause damage to the sealing ring or contaminate the medium. In addition, the material of the sealing ring cannot be corroded or undergo chemical reactions with the medium, which is also a special reminder from the sealing ring manufacturer.

4. When choosing the material of the sealing ring, in addition to paying attention to the speed of movement, pressure, and compatibility of the medium, temperature should also be taken into account. Temperature also has a certain impact on the material of the sealing ring. Either too high or too low temperature is not acceptable. If the temperature is too high, it will reduce the tensile strength and hardness of the sealing ring. If the temperature is too low, it will make the sealing ring very brittle. Each sealing ring material has its own suitable temperature range, which should also be noted.

Therefore, when choosing the material of the sealing ring, everyone must consider comprehensively. If it is difficult to choose for oneself, you can consult the sealing ring manufacturer.
