Among all soft colloids, silica gel is one of the materials with the best properties. It is comprehensive and high-quality in all aspects, so many industries choose to use it as the main body or spare parts. Food grade and ordinary grade are also divided into gas phase grade and precipitation grade. The difference between the two is that the compounds of the materials are different, and the main body is basically the same. For example, precipitated silica gel is mainly precipitated silica, which uses fuel gas to mix water glass made of quartz sand and soda ash at high temperature into a dilute solution with high concentration, and then adds certain compounds, which are washed, filtered and crushed to obtain precipitated silica. A precipitated silicone rubber raw material obtained by adding silicone oil, silica and other substances. The gas-phase silica gel is a gas-phase silica gel material obtained by adding silicone oil, white carbon black, siloxane and other substances into the sili...

Christmas and Halloween is coming soon, and the store has launched a new Christmas style of children's teether toys. Teeth gum styles include Santa Claus, Christmas tree, elk, Halloween pumpkin, gingerbread man, Christmas stockings, snowman and other lovely styles.  

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...
