Silicone products are closely related to our lives, and the safety of silicone products is a hot topic that people are concerned about. How to distinguish food-grade silicone from ordinary silicone, these few tricks are very practical!

Pull hard: When we see a silicone product, focus on a certain point of the product, and then pull it hard to both sides. If white is found, it is ordinary silicone, and if there is no white, it is food-grade silicone. Here is a simple example: For example, for a silicone cover, we can focus on a certain point with our hands and pull it back hard. If white is found, it means that the silicone cover is made of ordinary silicone, and if there is no white, it is made of food-grade silicone.

Smell: Regular silicone products should be made of food-grade silicone, which is non-toxic and odorless, and has no effect on the human body. Occasionally, the silicone will not turn white when pulled up, but there will be a faint smell. That is some residual smell left when the manufacturer produced it, not silicone. This residual smell will also disappear over time.

Fake silicone products are made of industrial-grade silicone, which will have a pungent smell and are toxic.

Hand feel: Silicone products made of food-grade silicone have good toughness and elasticity. They feel smooth when touched by hand and will not be permanently deformed by external forces. It is difficult for fake silicone products to achieve this effect. Silicone products made of non-food-grade silicone feel rough. This is because there is no layer of grease on the surface of fake silicone products.

Burning: Silicone burns with fire, and black smoke appears. The combustion product is black powder. It is a fake silicone product; white smoke appears, and the combustion residue is white powder. It is food-grade silicone.

Baking method: Except for special high-temperature resistant silicone, ordinary silicone can only withstand a maximum temperature of 150 degrees, while food-grade silicone can withstand a high temperature of 250 degrees and a high temperature of 350 degrees for a short time.

Certificate: This requires the manufacturer or merchant to provide FDA food-grade certification.

In addition to silicone products, there are also rubber and latex products. When choosing, we can try the elasticity of the product. The elasticity of rubber and latex is better than that of silicone, because silicone is relatively fragile. So if you find that the elasticity of the product is particularly good, it is a rubber or latex product rather than silicone. In addition, silicone products are generally colorless and transparent, while rubber and latex cannot be used to make transparent products because of the high impurity content. If you want to make transparent products, you must use silicone.
