The most frequently heard topic in daily life recently is that when choosing products made of silicone material, it is necessary to choose food grade silicone products, so that they are safe to use. It seems that people's awareness of this aspect is increasing nowadays, which is a good thing. However, people do not know what food grade silicone is? Not all silicone products in the market are made of food grade silicone materials. Today, I will explain to you what food grade silicone products are.
First of all, let me introduce the concept: Food grade silicone products are a type of abbreviation for inorganic polymer colloidal materials formed by the condensation of silicic acid. The main component is SiO2 · nH2O, which has a content of over 98%, is non-toxic, odorless, and has stable chemical properties. Moreover, under normal conditions, they do not react with any acid, alkali, or salt except for caustic soda and hydrofluoric acid.
Furthermore, in terms of the characteristics, properties, and uses of food grade silicone:
1、 The main characteristics of food grade silicone products:
1. Non toxic, odorless, high transparency, and non yellowing;
2. Soft and elastic, resistant to twisting and deformation;
3. Non cracking, long service life, cold and high temperature resistance;
4. Having higher tear resistance and superior electrical performance;
It has the advantages of high transparency, no smell, no yellowing and no frost spraying, especially solves the problems of black hose frost spraying and blue products fading, and has the advantages of softness, high tear resistance, high insulation, abrasion resistance, high temperature resistance, flame retardancy, anti-aging, environmental protection, tensile resistance, and stable performance.
2、 Performance of food grade silicone products:
1. Food grade silicone is a type of environmentally friendly silicone that is non-toxic, odorless, and highly transparent;
2. Soft, elastic, resistant to twisting and deformation;
3. No cracking, long service life, cold and high temperature resistance;
4. Having higher tear resistance and superior electrical performance;
5. Keep it unchanged at room temperature, do not spray frost, do not spit white, do not fade, and leave it in water for a long time without scale or odor;
3、 The main uses of food grade silicone products
At present, it is mainly used for food replica, chocolate mold, candy mold, precision casting, carbon fiber composite materials, food cake mold, craft ceramics, printing, human organ cloning, household appliances, lighting products, silica gel ice lattice, silica gel nipple.
With the increasing attention paid to food grade silicone products, it is believed that food grade silicone will appear in many places.
