Silicone products are becoming more more common in our lives, but a large number of people still have a better understanding of silicone products. Therefore, the editor will take you to learn more about food-grade silicone products ordinary silicone products.

　　 The raw materials of so-called silica gel products are silica gel, silica gel, also called silica gel, is a highly active adsorption material, which is an amorphous substance. The main component is silica, which is chemically stable. Silicone products are classified into many types according to their properties, such as food-grade silicone, medical-grade silicone, military-grade silicone, ordinary-grade silicone products. How to distinguish between food grade silicone products ordinary grade silicone products?

To distinguish them, we must first understand them. Food-grade silicone products use food-grade silica gel, which is an inorganic polymer colloidal material made by polycondensation of silicic acid. It is non-toxic odorless, high in transparency, stable in chemical properties, soft elastic. It is resistant to cold high temperature, has a strong water absorption capacity, has no toxic side effects to the human body. Ordinary silica gel products are made of ordinary silica gel, which has a great smell will turn yellow dark lines as time goes by.

In this way, it is relatively easy for us to distinguish between them. Food-grade silicone products are whitish, odorless, have a slight odor, soft to the touch, the burnt gray is white, while ordinary silicone products are whitish have a lot of A big smell, the burnt ash is black.

　　Because of the different needs of each industry, the silicone products used will also be different. to mention that food grade silica gel must be better than ordinary grade silica gel. Each has its own advantages.
