Silica gel for food is an inorganic polymer colloid material condensed by silicic acid. Its main component is SiO2·nH2O, its content is over 98%. It is non-toxic and tasteless, and its chemical properties are stable. Under normal conditions, it does not react with any acid, alkali or salt except caustic alkali and hydrofluoric acid. Because it is a colloidal structure, it has many micropores and large specific surface area. Generally, the service life of silica gel tableware is more than three or five years, because the silica gel tableware is produced from food-grade silica gel raw materials, and it has passed FDA, lfgb and SGS certification tests, meeting the food-grade standard certification. Silicone tableware is nontoxic, odorless, flexible, high and low temperature resistant, and can be used in the temperature environment of -40℃~230℃. It is wear-resistant, corrosion-resistant, aging-resistant, durable, and more suitable for non-stick pans. Silica gel tableware is at the r...
