Activated Molecular Sieve Powder, Desiccant Powder for Moisture Removal

Activated Molecular Sieve Powder – 3A, 4A, 5A and 13X for Industrial Moisture and Gas Adsorption

Product Overview

Shanghai Zixuan Technology Co., Ltd. supplies Activated Molecular Sieve Powder in 3A, 4A, 5A and 13X types for industrial drying, moisture removal, gas purification and adsorption applications.

Molecular sieve activated powder is a fine-particle adsorbent with a uniform microporous structure and selective adsorption properties. It can selectively adsorb water molecules and other target molecules according to its pore size and molecular structure.

Compared with granular molecular sieves commonly used in packed adsorption towers, activated molecular sieve powder is suitable for applications where the adsorbent needs to be dispersed or incorporated into other materials during manufacturing.

The four available types offer different pore sizes and adsorption characteristics, allowing customers to select a suitable grade according to their application requirements.

Available Types and Applications

1. 3A Activated Molecular Sieve Powder

Nominal Pore Size: 3 Å

3A molecular sieve powder is primarily used for selective water adsorption. Its small pore opening allows water molecules to enter while restricting the adsorption of many larger molecules.

Typical applications:

• Moisture removal from solvents and organic liquids

• Drying of polyurethane raw materials

• Moisture control in insulating glass sealants and related materials

• Industrial chemical drying

• Moisture-sensitive coating and adhesive formulations

2. 4A Activated Molecular Sieve Powder

Nominal Pore Size: 4 Å

4A molecular sieve powder is a general-purpose adsorbent with strong affinity for water molecules. It is widely used in industrial drying and moisture-control applications.

Typical applications:

• Industrial gas and liquid drying

• Moisture removal from solvents

• Drying of refrigerants and chemical raw materials

• Moisture control in paints, coatings and adhesives

• General-purpose moisture scavenging applications

3. 5A Activated Molecular Sieve Powder

Nominal Pore Size: 5 Å

5A molecular sieve has a larger pore opening than 3A and 4A types. It is known for its selective adsorption of suitable molecular species, including normal paraffins, under appropriate adsorption conditions.

Typical applications:

• Selective adsorption and separation processes

• Hydrocarbon separation

• Normal paraffin adsorption

• Specialized gas and chemical purification applications

4. 13X Activated Molecular Sieve Powder

Nominal Pore Size: 10 Å

13X molecular sieve has a relatively large pore opening and a broad adsorption capability. It is commonly used for the adsorption of water, carbon dioxide and other suitable molecules.

Typical applications:

• Moisture and carbon dioxide removal

• Industrial gas purification

• Air and process gas drying

• Adsorption-based purification systems

• Chemical and petrochemical processing applications

Key Product Features

• Multiple grades available: 3A, 4A, 5A and 13X.

• Selective adsorption: Different pore structures provide different molecular adsorption characteristics.

• Fine powder form: Suitable for applications requiring powder-form adsorbents.

• Moisture control: Suitable for drying and moisture-scavenging applications.

• Application flexibility: Different grades can be selected according to the target molecules and process requirements.

Product Specifications

Detailed technical specifications, including particle size distribution, moisture content, bulk density and adsorption capacity, should be confirmed according to the selected product grade and Technical Data Sheet (TDS).

Typical Industries

• Chemical and petrochemical industry

• Polyurethane and polymer manufacturing

• Paints, coatings and adhesives

• Insulating glass manufacturing

• Refrigerant and solvent drying

• Industrial gas purification

• Other moisture-sensitive manufacturing processes

Product Selection

The appropriate molecular sieve powder should be selected according to the target substance, required moisture level, compatibility with the formulation, processing temperature and application method.
