Recently, I heard the most topic that we must choose food grade silicone materials to ensure safety. It seems that people are more and more aware of this aspect, which is a good thing. However, we don't know what food grade is. Not all silicone materials are food grade silicone materials.






Food grade silica gel product is an abbreviation of inorganic polymer colloidal material formed by the condensation of silicic acid. Its main component is SiO2 · nH2O. Its content is more than 98%. It has the characteristics of non-toxic, tasteless, stable chemical properties, etc. Besides caustic soda and hydrofluoric acid, it does not react with any acid and alkali under normal conditions.






1、 The main characteristics of food grade silicone products are as follows:






1. Non toxic, odorless, high transparency and no yellowing;






2. It's soft, elastic, resistant to kink and deformation; (especially suitable for baby, don't worry about breaking and knocking)






3. No cracking, long service life, cold and high temperature resistance;






4. It has higher tear strength and superior electrical performance;






It has the advantages of high transparency, no smell, no yellow, no frost and so on. In particular, it solves the problems of black hose spraying and blue products fading, soft, high tear resistance, high insulation, wear resistance, high temperature resistance, flame retardant, anti-aging, environmental protection, tensile type, stable performance and so on.






2. Properties of food grade silica gel products






1. Food grade silica gel is a kind of environmental silica gel, non-toxic, odorless, high transparency;






2. Soft, good elasticity, anti kink and no deformation;






3. No cracking, long service life, cold and high temperature resistance;






4. It has higher tear strength and superior electrical performance;






5. No yellowing, no frost, no white, no fading, no scale and no peculiar smell when placed in water for a long time;






3、 Main uses of food grade silica gel products






At present, it is mainly used for household silicone products, candy molds, food cake molds, household appliances (keyboard, silicone keys), silicone ice lattice, silicone pacifier, silicone bowl, silicone shovel, silicone fresh-keeping cover, silicone gloves, silicone insulation pad, etc.














Of course, medical silica gel products are indispensable for the safety of silica gel products, such as silica gel for blood oxygen analyzer, silica gel for ventilator, silica gel protective cover, silica gel sealing ring, etc.














As people pay more and more attention to food grade silicone products, silicone products are becoming more and more diversified, personalized and humanized. Let's look forward to more silicone products and the convenience they bring us in the future.
