Blue Indicating Function
This product is a moisture absorbing material with color indicating function. Its main feature is that it can indicate the moisture absorption state through color changes. Under the initial dry conditions, this product shows a blue color. When the moisture absorption is saturated, its color will change from blue to pink. The color indicating function can give you more convenient operation. The intuitive color change can help you judge the state in real time. Therefore, you can replace or regenerate the desiccant in time to keep the storage environment dry more effectively.
Safety
We use non-toxic and harmless materials that meet international safety standards. The particles are odorless and non-corrosive. They do not cause any damage to equipment and stored items. In addition, they have extremely high chemical stability. During use, they do not produce harmful gases or residues. Under normal conditions of use, this product will not affect human health and protect the safety of stored items.
Moisture Absorption Rate
Due to its excellent moisture absorption performance, this product can still work effectively in a high humidity environment. Its moisture absorption rate can reach 30%-40% of its own weight. It can quickly absorb moisture in the air in a short period of time, and significantly reduce the ambient humidity.
Applicable Scenarios of Blue Indicating Silica Gel Desiccant
This blue indicating silica gel desiccant is very suitable for occasions where real-time monitoring of the drying status is required. The following are the scenarios where this product is preferred:
1. Electronic Equipment Protection: cameras, hard disks and other devices that are susceptible to moisture
2. Laboratory Environment: storage of chemical reagents, documents or other items that are sensitive to moisture
3. Home Storage: clothing, books, collections, etc.
4. During Transportation: when transporting food, medicines or electronic products, etc.
Custom Service
We provide customized service. You can adjust the particle size, packaging material, moisture absorption rate, color change and other parameters according to your needs. In addition, we support corporate logo printing and special packaging (such as non-woven fabrics, Tyvek® breathable film, etc.)
