Food grade silicone tube is not suitable for direct contact with open flames. Although silicone has good high temperature resistance and can withstand temperatures up to 200 ° C or higher in most cases, its fire resistance is limited. Direct contact with open flames can cause the silicone tube to rapidly heat up beyond its tolerance limit, which may lead to the melting, deformation, decomposition, or production of harmful substances of the silicone gel.
When silicone tubes comes into contact with open flames, high temperatures can damage its molecular structure, causing material aging or structural instability. Although silicone is resistant to high temperatures, it does not have fire resistance and is not suitable for prolonged exposure to direct fire sources. Therefore, in order to protect the performance and safety of food grade silicone tubes, it should be avoided to expose it to fire sources or extreme high temperature environments.
If silicone tubes needs to be used in high-temperature environments, it is best to ensure that the tubes is kept at a certain distance from open flames or high-temperature sources, and avoid direct contact with flames. In addition, it is also possible to consider adding an external protective layer to the silicone tube during use to prevent it from being damaged by heat. In short, although silicone has high temperature resistance, it is not suitable for direct contact with open flames, and this situation should be avoided during use.
