4A molecular sieve activated powder is a high-performance desiccant material designed for efficient moisture control in industrial applications. Featuring a precisely engineered microporous structure, it selectively adsorbs water molecules while preventing the uptake of larger molecules, ensuring superior drying performance and chemical stability. This material is widely used in coatings, adhesives, insulating glass production, and fine chemical synthesis, delivering reliable moisture adsorption for continuous industrial processing.
Product Overview
4A molecular sieve activated powder is derived from the calcination of 4A molecular sieve powder at high temperatures. During calcination, most of the structural water is removed, significantly enhancing its activity and transforming it into a highly active adsorbent with strong selective adsorption properties. This product is widely used in various industrial processes, particularly in the production of polyurethane, coatings, resins, and certain adhesives. It effectively adsorbs moisture, CO₂, H₂S, and other gaseous impurities, ensuring stable product quality.
Key Features
- High Activity: The calcination process imparts stronger adsorption capacity, making the powder suitable for a wide range of adsorption applications.
- Selective Adsorption: Strong selective adsorption of moisture and other impurities ensures higher product quality.
- No Alteration of Physical/Chemical Properties: While adsorbing impurities, the product does not alter the physical or chemical properties of the material, ensuring stable production.
- Multifunctionality: Used to improve material uniformity, eliminate bubbles, and enhance strength in a variety of applications.
Applications
- Polyurethane Production: Used to adsorb moisture and impurities without affecting the physical or chemical properties of the product, thus improving the quality of polyurethane products.
- Coatings and Paints: As an additive or filler, it effectively reduces moisture, eliminates bubbles, and improves material uniformity and strength.
- Resins and Adhesives: Used in resin and certain adhesive production processes to enhance product performance and stability.
- Insulating Glass Drying: Can be used as a drying agent in insulating glass composite sealants to absorb moisture.
- Catalyst Support: Functions as a catalyst support in petroleum refining, petrochemical processes, and environmental management applications.
