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.
Adopting DuPont paper (Tyvek) as the packing material, it is high strength, light weight, tough and tear resistant. It has strong permeability, no re-infiltration, moisture-proof, anti-static, and non-sticky ash. The product is non-toxic and non-hazardous, neutral and non-moldy. Only carbon dioxide and water vapor are left after complete combustion, which is a very good environmental protection product. It does not work on most acids and alkalis.
It is printed with water-based ink that meets the relevant requirements of FDA 21CFR, which is safe and reliable, and the text is clear and does not lose color.
The packing material is sterilized by UV light to ensure the quality of the product from the source. Checked under 365nm and 254nm UV lamp, no flake fluorescence appears.
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.
