Industrial Silica Gel Suppliers

This industrial silica gel is a highly active adsorption material. Its main component is silicon dioxide (SiO2), which has the characteristics of porous structure, stable chemical properties, high mechanical strength, high temperature resistance and strong adsorption. This desiccant is widely used in the drying, adsorption, catalysis, and separation in many industrial fields. It is an important auxiliary material in the petrochemical, electronic manufacturing, pharmaceutical and environmental protection industries.

Noted: We can custom desiccant for specific applications.

Product Features

1. Highly efficient adsorption. Porosity up to 70%. It can quickly absorb moisture, organic vapor and harmful gases.

2. Strong thermal stability. Wide temperature range (-40℃ to +200℃). Stable performance at high temperatures.

3. Chemical Inertness: insoluble in water and most solvents. Acid and alkali corrosion resistance. Safe and non-toxic.

4. Various Physical Forms: transparent or translucent particles, spheres, blocks, etc. The specifications of the industrial silica gel can be customized according to needs.

Moisture Absorption Rate Under Standard Conditions

1.25°C, Relative Humidity 60%:

Ordinary Silica Gel (Coarse Pore Type)

The moisture absorption can reach 20%~30% (every 100g of silica gel absorbs 20~30g of water).

Fine Pore Silica Gel

The moisture absorption is higher, about 30%~35%.

2. High Humidity Environment (RH 90%):

The moisture absorption rate can be increased to more than 40%.

Cost-Effectiveness

Our industrial silica gel has higher cost-effectiveness. Firstly, you can spend less on raw material costs, because we have mature production processes. Secondly, the moisture absorption rate of silica gel desiccant is much higher than that of traditional desiccants, such as calcium chloride or natural clay. Its unit moisture-proof cost is lower. The reusable feature significantly reduces long-term procurement costs.

During the moisture absorption process, this silica gel will not dissolve, expand, or corrode the packaging. The use of this desiccant can reduce the risk of damage to stored items. In large-scale warehousing or transportation, this desiccant can stabilize and control moisture for a long time, reducing the cost of goods scrapping or equipment maintenance caused by moisture.
