silicone ice cube molds provided by our factory is made of food grade silicone.But what is Food Grade Silicone?This article will do a analysis material characteristic of Food Grade silicone.Food Grade silica gel is an inorganic polymer colloidal material formed by silicic acid condensation. Its main component is mSiO2nH2O. The material is chemically stable and does not react with any acid or base except caustic soda and hydrofluoric acid.Silica gel ice lattice is generally non-toxic and tasteless, the composition of silica and water, safe and stable. Silicone products are resistant to high temperature, low temperature, safe to use, even when burnt, will only decompose into silica and water vapor, non-toxic and harmless. Anti – aging, non – fading, oxidation decomposition temperature far more than similar Plastic products.
