shipping containers silica gel manufacturers

Our shipping containers silica gel is a highly efficient moisture-absorbing and moisture-proof product. It is specially designed for shipping containers and long-term storage environments. Its main component is highly active silica gel particles. This silica gel particle can quickly absorb excess moisture in the container. Therefore, it can prevent the goods from getting damp, mildew and rust. Ensure the safety of goods during transportation and storage.

Noted: We can custom silica gel desiccant for specific application.

Usage Application	Protecting cargo in shipping containers against humidity and condensation, preventing mold or corrosion

Moisture Absorption Capacity

Our shipping containers silica gel can absorb 30% to 40% of its own weight in water. At 25°C and 90% relative humidity, 1 kg of silica gel can absorb about 300 to 400 grams of water. At the same time, this desiccant absorbs moisture faster and more effectively under high humidity conditions. It is very suitable for facing high humidity and temperature changes in ocean transportation, protecting goods from water vapor damage.

Product Advantages

1. Strong Moisture Absorption

We use high-quality silica gel material. Its moisture absorption rate is as high as 30% or more. This desiccant can effectively reduce the humidity in the container. It avoids the formation of condensation water ("container rain").

2. Safety and Environmental Protection

Non-toxic and odorless. It complies with international environmental standards such as REACH and RoHS, etc. It does not damage the goods. It is suitable for sensitive goods such as food, electronic products, textiles, etc.

3. Long-Term Protection

After absorbing moisture, the silica gel particles do not deform or leak. The continuous action time is up to 30-90 days (depending on the ambient humidity).

4. Convenient to Use

We provide independent packaging design for shipping containers silica gel. Common specifications: 500g/1000g/2000g bagged or hanging. You can hang it directly on the inner wall of the container or lay it flat on the top of the cargo. No additional operation is required.

5. Widely Applicable

These desiccants are suitable for a variety of scenarios, such as sea transportation, rail transportation, and long-term storage. They can protect a variety of goods, such as metal equipment, furniture, paper, clothing, etc.

Applicable Scenarios

1. Shipping Containers: This shipping containers silica gel prevents condensation damage caused by high humidity or temperature difference.

2. Warehousing Moisture-Proof: It protects raw materials or finished products that need to be stored for a long time.

3. Precision Instruments/Electronic Products: It prevents circuits from being oxidized by moisture.

4. Furniture/Textiles: It prevents mildew and odor.
