How to correctly heat silicone sealing rings?

Silicone sealing rings, as an important sealing component widely used in the industrial, medical, and food fields, generally do not produce harmful substances during the heating process. But if the silicone sealing ring is not heated properly, it can also have adverse consequences. Below, we will introduce the effects of improper heating of silicone sealing rings and how to correctly heat them.

1. Odor generation: Within a certain temperature range, the silicone sealing ring may emit an odor when heated, which is caused by the thermochemical reaction of the silicone material molecules. These odors are usually not harmful to the human body, but ventilation is necessary when heating.

2. Deformation risk: If the heating temperature is too high, the silicone sealing ring may soften and deform, affecting its sealing performance. Therefore, it is necessary to control the heating temperature during use to avoid excessive heating.

1. Temperature control: Avoid exceeding the maximum operating temperature of silicone material. Generally speaking, the maximum temperature that silicone sealing rings can withstand is about 200 ℃.

2. Cleaning treatment: Before heating, thoroughly clean the impurities and oil stains on the surface of the silicone sealing ring to ensure better heating effect.

3. Ventilation maintenance: Maintain good ventilation during the heating process to avoid the retention of odors.

4. Avoid direct contact with high-temperature surfaces: When heating, avoid direct contact between the silicone sealing ring and open flames or high-temperature metal surfaces. Hot air blowing or adding water to containers with silicone sealing rings can be used for heating.

Overall, silicone sealing rings do not produce significant harmful substances under normal heating conditions, but potential risks during heating should still be treated with caution and the correct usage methods should be taken to ensure safety.
