Silicone products are becoming more and more common in our lives, but a large number of people still have a superficial understanding of silicone products. Therefore, our Rongjin silicone manufacturer will take you to learn more about food-grade silicone products and ordinary silicone products.
The raw materials of so-called silica gel products are silica gel, and 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 divided into many types according to their properties, such as food-grade silicone, medical-grade silicone, military-grade silicone, and ordinary-grade silicone products. How to distinguish between food grade silicone products and 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 formed by polycondensation of silicic acid. It is non-toxic and odorless, high in transparency, stable in chemical properties, soft and elastic. It is resistant to cold and high temperature, has a strong water absorption capacity, and has no toxic side effects on the human body. Ordinary silica gel products are made of ordinary silica gel, which has a great odor, and will turn yellow or dark lines over time.

In this way, it is relatively easy for us to distinguish them. Food-grade silicone products are not whitish, odorless, or have a slight odor. A big smell, the burnt ash is black.
Because of the different needs of the industry, the silicone products used will be different. Not to mention that the food grade silica gel must be better than the ordinary grade silica gel. They each have their own advantages.
