Blue silica gel has the adsorption and moisture-proof effect of narrow pore silica gel, It is characterized by the moisture absorption process, it can become light blue with the increase of moisture absorption, and finally become light red or light pink. It can indicate the humidity of the environment and also visually show whether a new desiccant needs to be replaced.

Blue Silica Gel

1 gram of silica gel desiccant

The main raw materials of industrial desiccant are: narrow pore silica gel, B-type silica gel, color-changing silica gel,active mineral balls, montmorillonite, molecular sieve and so on. Users can choose according to the type characteristics of packaging products.

Column Chromatography Silica Gel

Column chromatography silica gel is white powder, the main component is SiO₂·nH₂O, insoluble in water, inorganic acid and other organic solvents, soluble in HF and concentrated caustic soda solution. It absorbs moisture in the air.Because of the difference in adsorption and retention time of different substances, various substances can be separated and purified.

Medicinal & Food Desiccant

The medicinal silica gel desiccant conforms to the standard of YBB00122005"Medicinal silica gel desiccant in solid paper bags". The medicinal desiccant is filled with silica gel. According to the weight is divided into 0.5g, 1g, 2g, 3g, 5g, 10g, 20g, 50g, etc., can be processed into various specifications according to customer requirements. According to the shape is divided into:bag, roll, etc. Packaging materials: composite paper, tea paper, OPP, Aihua paper, Dupont paper, etc.

Calcium Chloride Desiccant

Calcium chloride desiccant is a commonly used humidity-absorbing material, primarily used to adsorb moisture in the air and reduce humidity. Its main principles are as follows:
1. Hygroscopic Reaction: Calcium chloride has strong hydrophilicity. When exposed to humid air, it absorbs moisture from the surrounding environment through a hygroscopic reaction. This occurs because calcium chloride's structure contains hydrates that form compounds with environmental moisture, thereby adsorbing water.
2. Moisture Absorption Capaciy: As a desiccant, calcium chloride has high moisture absorption capacity and can continuously absorb humidity from the air until it reaches saturation.

In 1998, the European Union identified cobalt chloride as a class II carcinogen, blue gum containing cobalt chloride has been banned in Europe and the United States and phased out, in order to meet the needs of the market, the development of cobalt-free environmental color-changing silica gel.

Orange silica gel

The purple-red color-changing silica gel is purple-red color when dry, gradually turns orange-red after moisture absorption, and light orange upon full saturation. Can easily check its moisture saturation by observing color changes. The product is cobalt-free, environmentally safe, chemically stable and highly adsorptive.

Purple-red silica gel

Silica Gel for Flower Drying

Flower desiccant is a microporous silica material, that is safe, odorless, and has stable chemical properties. It exhibits excellent hygroscopic capacity. Combine with blue indicating silica gel or orange indicating silica gel, it smoisture absorption is visible, allowing for intuitive judgment of the drying state of flowers. Additionally, it is reusable.
Using this desiccant shortens the drying period for flowers and effectively maintains the original color and shape of the petals. After drying, the flowers or bouquets should be stored in a dry environment to prevent moisture absorption.

CORE ADVANTAGES

Application Areas · Quality-Driven Excellence · Serving Customers Nationwide

医药制造

Used for moisture-proof packaging of pharmaceutical bottles, traditional Chinese medicine, and medical devices, pharmaceutical desiccants help keep medications dry, reduce the risk of moisture absorption, and contribute to maintaining drug stability.

生物化工

Silica gel for column chromatography and thin-layer chromatography is used in industrial purification, natural product isolation, and chemical analysis and detection; as an adsorbent, it can meet the demands of high‑precision separation and purification.

电子电器

It can be used in electronic product packaging, precision instruments, and communication equipment to absorb ambient moisture, thereby reducing the risk of circuit board oxidation and corrosion of metal components.

食品加工

It provides physical moisture protection inside food packaging, reducing the risk of spoilage caused by moisture absorption in products such as pastries, seaweed snacks, and dried goods, thereby helping to maintain their crisp texture.

家居日用

Color-changing silica gel is used for humidity monitoring and moisture protection in home wardrobes and shoe cabinets; scented silica gel helps deodorize and freshen spaces such as shoe cabinets and car interiors, enhancing the ambient air quality.
