This product is different kinds of silica gel packaged in moisture-permeable sachets. The main raw material silica gel is a kind of high-pore structure water-containing silica, non-toxic, tasteless, odorless, chemically stable and highly active adsorption material, with strong moisture absorption performance. Therefore, it is widely used to control the relative humidity of the environment in the storage and transportation of instruments, meters, equipment, leather, luggage, footwear, textiles, food, medicine, etc., to prevent items from being damp, mildew, and rust. Silica gel is an amorphous material. Its chemical formula is mSiO2.nH2o. It is insoluble in water and any solvent. It is non-toxic, odorless and stable in chemical properties. It does not react with any substance except strong alkali and hydrofluoric acid. The chemical composition and physical structure of silica gel determine that it has many characteristics that are difficult to replace by other similar materials: high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. The interior of the silicone desiccant is a very fine pore network structure. These pores can absorb moisture and retain moisture through its physical attraction. Aviation components, computer devices, electronic products, leather products, medicine, food and other industries . Even if the desiccant is completely immersed in water, it will not soften or liquefy. It is non-toxic, odorless, non-corrosive, and non-polluting, so it can be in direct contact with any item.
