Zeolite Molecular Sieves Activated Powder Desiccants Adsorbents
Molecular Sieve Activated Powder Introduction
Molecular sieve activated powder is produced by high temperature calcination of molecular sieve raw powder. Because the raw powder of molecular sieve loses most of its water during the high-temperature calcination process, the activated zeolite powder has strong activity and can be directly applied in production as an adsorbent with selective adsorption.
Molecular sieve activated powder is widely used in the production of polyurethane and other polymers, which can adsorb impurities such as water that affect product quality without changing the physical and chemical properties of the product itself. It can also be added as a selective adsorbent to specific polymers or coatings in the production process to adsorb CO2, H2S and other gases produced in the growth process. Some powdered molecular sieves can also be applied to insulating glass composite strips as desiccant or as catalyst carriers.

Molecular Sieve Activated Powder Applications
3A Activated Powder Desiccants
- Added to the insulating glass composite strip as an amorphous desiccant
- Polyurethane production (coatings, painting, adhesives, sealants) to avoid foam formation
4A Activated Powder Desiccants
- Be used in additives or aggregates of coatings, paints, resins and some adhesives to reduce moisture
- Eliminate air bubbles, improve material uniformity and strength
- Production of polyurethane products, adsorbs the impurities such as moisture that affect product quality
- Not changing the physical and chemical properties of the product
5A Activated Powder Desiccants
- Production of polyurethane products, adsorbs the impurities such as water that affect product quality
