Food grade silicone rubber daily necessities have irreplaceable characteristics. First, non-toxic and tasteless is basic. Second, the service life and performance must be outstanding. Compared with other ordinary materials, the difference is that they are resistant to high temperature and deformation, and have stronger toughness. For example, they will not bump after falling, can bend for a long time, knead, do not stick oil stains, and will not mildew and discolor after being placed for a long time. This is what ordinary materials cannot compare with other materials.

Silicone rubber is widely used in food. All kinds of silicone rubber kitchenware and tableware can be produced, and they are absolutely qualified. In fact, food grade silicone rubber has been found in ordinary people's homes. The common one is the gasket used for sealing in the pressure cooker, which is easy to clean and non-toxic. It can be seen everywhere in the kitchen appliance industry. Take the silicone rubber shovel as an example. Its characteristics are that it can be bent and fit the bottom of the pot better. Its characteristics of water resistance, oil resistance, non stick to the pot and easy cleaning are also popular with consumers. The silicone rubber pacifier will not deform or produce peculiar smell even if it is boiled in boiling water. It has many advantages, so it has become the choice of many parents.

Do you know how to identify food grade silicone rubber?

Secret 1: Smell. If you smell the silicone rubber products close to your nose, you will find that ordinary silicone rubber has a pungent smell, otherwise it is food grade silicone rubber. The ordinary silicone rubber has a pungent smell, which belongs to the non environmental silicone rubber. Food grade silicone rubber is non-toxic and tasteless, and belongs to environmental silicone rubber.

Secret 2: Pull hard. Take the silicone rubber tube as an example. Hold the two ends of the silicone rubber tube with your hands and pull it in the opposite direction. If it turns white and can smell pungent, it means it is ordinary silicone rubber. On the contrary, it is food grade silicone rubber. (Sometimes it will not turn white when pulled up. Because the manufacturer has by-products generated during the production and vulcanization process, it will have a faint smell, but it is also food grade silicone rubber, which will not affect the product quality, and this smell can be eliminated by itself.).

Secret 3: Baking method. Except for special silicone rubber, the temperature resistance of ordinary silicone rubber can only be up to about 150 ° C, while that of food grade silicone rubber can be up to 250 ° C and 350 ° C in a short time.

Tip 4: Ask manufacturers or businesses to improve FDA food level certification.
