Silica gel has high stability in high temperature environment and can be used safely. However, it is important to note that the specific temperature tolerance of silicone products may vary by manufacturer and product type, and it is recommended to check the product's instruction manual before use. As for whether the silicone will be toxic after heating, we can rest assured that food-grade silicone is usually safe.
Food-grade silicone needs to meet extremely strict environmental standards in the production process to ensure that it will not cause any toxicity to users.
Therefore, food-grade silicone products are generally safe under prolonged high temperature heating. However, it should be noted that it is best to avoid exceeding the temperature range of silicone when used to ensure the stability and safety of the product
