Food-grade silica gel will not be toxic when heated at high temperature for a long time.
The silica gel itself is very stable, and if it has passed the food grade, it will not change easily, but it is necessary to pay attention to the use of the environment, and try not to use a high temperature of more than 250 degrees to bake.
As the name suggests, food-grade glue is an environmentally friendly glue that can reach the edible level, which can be seen that this glue is extremely strict in the production requirements, and the unique food-grade glue can be widely used in various food packaging, various household kitchen utensils, and food machinery, and will not cause any toxicity to the user's body in contact.

1. Silicone can be cleaned with water, if it is not so smooth and uneven, we can find a small brush to clean gently; If cleaning is really not possible, you can use soap to apply it to it;
2. If it is the kind of silicone that dissipates heat, we can use alcohol to remove it;

Food-grade silicone resin is an inorganic polymer colloidal material made of polycondensation of silicic acid, the main component is SiO2·NH2O, its content is more than 98%, non-toxic and tasteless, and the chemical properties are stable; Non-toxic, odorless, high transparency, non-yellowing, this is its characteristics, will be used in food or edible; If there is a peculiar smell, it is recommended not to drink water, it may be caused by the impurity of the resin and the PP material of the water cup body, for the plastic water cup, it is recommended to buy brand products, such as Lock, if there is a peculiar smell, do not use, and can not use hot water many times, which is the same as the beverage bottle can not be filled with hot water and can not be used many times.

This method is very simple, and you can experiment with it when you see the product. Visual inspection is fine. How it works:
Hold the silicone product in your hand, focus on one spot, and pull firmly to both sides. What appears white is ordinary silicone, and what does not appear white is food-grade silicone.
Sniff] Put your nose close to the silicone product and smell it. If it is whitish and has a pungent smell when pulled, then it can be concluded that it is ordinary silicone, not food grade.
Finally, silicone will say two points that need to be noted.
1. The main methods of identification are very simple and practical visual inspection, whitish when pulled up, and there is a pungent smell, which can be concluded to be ordinary silica gel, which does not meet the food grade standard.
2. Note that the silica gel is not whitish when pulled up, but it also has a faint smell, and it is also food-grade, because it is produced in the production process of the manufacturer, which does not affect the quality of the product and can be eliminated by itself.
It depends on what you use it for, if the food grade meets your requirements, there is no need to use the medical grade, each has its own requirements and standards.
There should not be many manufacturers of food-grade stainless steel pipes, and it is generally Angang Masteel to find a big brand.
