Silica gel desiccant is a kind of highly active adsorbent material, which is the most commonly used desiccant. It belongs to amorphous substance, its chemical molecular formula is mSiO2.nH2O. it is insoluble in water and any solvent, non-toxic, tasteless, chemically stable, and is a very safe, physical adsorption type desiccant, which can absorb and lock moisture through its own internal microporous structure (moisture absorption rate can reach 30%), and does not damp decompose after absorbing moisture. It has the characteristics of non-toxic, tasteless, non-corrosive and non-polluting, so it can be in direct contact with any articles.
Indicating(orange) silica gel desiccant beads are added to the raw material, and the orange beads gradually turn into green after absorbing moisture, and the color change process of the beads can be viewed through the transparent window on the back of the product.
The production meets GMP requirements and has GMP certificate. It conforms to China YBB00122005 solid paper bag silica gel desiccant standard (State Drug Package Registration No.: B20190000354) and conforms to U.S. FDA drug desiccant standard (FDA DMF No.: 31936). At present, it is mainly used in pharmaceutical industry.
