Is The Transparent Silicone Desiccant In Food Poisonous?

- Apr 15, 2020-

    The transparent desiccant is called silica gel desiccant or glass desiccant. The dried silica gel desiccant easily absorbs water. This desiccant is non-toxic and environmentally friendly. There are three common desiccants used in life: silica gel with transparent particles, lime, and mineral desiccant. Silica gel desiccant is an environmentally friendly, non-toxic and moisture-proof product. The product quality fully meets ROHS and REACH and other environmental requirements. It does not contain harmful substances such as DMF (dimethyl fumarate).


    Silica gel desiccant is a highly active adsorbent material. After some treatment, silicic acid is an amorphous substance with chemical formula mSiO2, nH2O, no water and any solvent, non-toxic and tasteless. The chemical property of silica gel desiccant is stable, it will not react with anything other than strong alkali and hydrofluoric acid. Due to their different manufacturing methods, various types of silica gel have different microporous structures. The chemical structure and physical structure of silica gel determine that it has many characteristics that are difficult to replace other similar materials: strong adsorption performance, good thermal stability, stable chemical properties and other safety properties.

    Silica gel desiccant is a physical adsorption desiccant. Silica gel absorbs moisture in the air through the principle of physical adsorption and does not react with water. There are many types of desiccants, divided into physical adsorption and chemical adsorption. Chemical adsorption of calcium oxide, calcium chloride or phosphorus pentoxide, silicic acid. Physical adsorption: silica gel, montmorillonite, minerals, etc.
