This silica gel white is an ideal moisture-proof solution. This package is filled with high-purity silica gel, with a translucent or white granular appearance. Its unique microporous structure can quickly absorb moisture from the surrounding environment. Therefore, this desiccant can effectively control humidity, and prevent products from getting damp, mildew or oxidation.

Noted: We can custom desiccant for specific applications.

Product Features and Advantages

1. It complies with international safety standards such as FDA and EU. And it does not contain cobalt chloride.

2. White silica gel. No color change. More suitable for scenarios with high purity requirements.

3. It only absorbs moisture. It does not react chemically with the protected items, ensuring high safety.

4. In an environment with a relative humidity (RH) of 90%, the moisture absorption rate can reach 30%-40%, far exceeding ordinary desiccants.

5. High temperature resistant (≤200℃). No decomposition. No volatility. Long-term use does not affect performance.

6. Heating can desorb moisture. Reusable silica gel white. Reduce the cost of use.

Moisture Absorption Rate

1. In an environment with a relative humidity of 20%, the moisture absorption rate is about 6%-8% (weight ratio);

2. At a relative humidity of 50%, the moisture absorption rate can reach 15%-20%;

3. In a high humidity environment with a relative humidity of 90%, the moisture absorption rate can rise to 30%-40%.

Regeneration Ability

When heated to 100-120℃, this silica gel white can release the absorbed moisture and restore its hygroscopic properties. It can be reused.

Application Scenarios

Selection Suggestions

1. High-Value Items (such as electronics and medicine): High-purity silica gel white is preferred to avoid contamination by impurities.

2. For food-related applications, it is necessary to choose desiccants that meet food-grade standards (such as FDA and EU).

3. Long-Term Storage: It is recommended to use a humidity indicator card, and replace or regenerate the silica gel regularly.
