Introduction:

Chunwang Pharmaceutical Desiccant uses brand new transparent silica gel desiccant particles as raw materials. Silica gel desiccant is a highly active adsorbent material and is the most commonly used desiccant. It is an amorphous substance with a chemical formula of mSiO2·nH2O, conforming to the Chinese chemical standard HG/T2765-2005. It is the only desiccant approved by the FDA for direct contact with food and pharmaceuticals. Silica gel desiccant has a strong moisture absorption capacity and excellent adsorption performance; even when fully immersed in water, it does not soften or liquefy. It is non-toxic, odorless, non-corrosive, and non-polluting, making it safe for direct contact with any items.

The materials and manufacturing process of this product meet pharmaceutical-grade standards. The production procedures comply with GMP guidelines and are GMP certified. The product conforms to the U.S. FDA standards for pharmaceutical desiccants (Registration No. 31936) and meets the standards of the U.S. Pharmacopeia USP41-NF36. Additionally, it has obtained national drug packaging material registration (Registration No. B20190000354).

Pharmaceutical Grade Desiccant Packs

The packaging material is made from Tyvek, produced by DuPont in the U.S.
It features unidirectional breathability.
It is tear-resistant, anti-aging, lint-free, resistant to acids and alkalis, and prevents dust leakage.

Pharmaceutical Grade Desiccant Canisters

The container is made of PP plastic, eliminating the risk of fiber contamination.
The material has high strength, making it sturdy and pressure-resistant.
Its uniform mesh-like structure ensures a stable moisture absorption rate.
