Product Description

Chemequip New Material Ltd.

Molecular Sieve Activated Powder is produced by high temperature roasting of molecular sieve raw powder. Because the raw powder of molecular sieve loses most of its water during the high-temperature roasting 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.

3A Activated Powder Desiccants

•  Be added to the insulating glass composite strip as an amorphous desiccant
•  Be used in polyurethane products (coatings, adhesives, sealants) to avoid foam formation and extend the service lifetime

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
•  Not changing the physical and chemical properties of the product itself
•  Selective adsorbent for polymers or coatings to adsorb CO2, H2S and other gases.

13X Activated Powder Desiccants

•  As a functional filling material used in the pharmaceutical and food industries
•  As an additive for rubber, plastic, paint, coating and cosmetics industries

Storage
Prevent the molecular sieves from exposing directly to the damping environment and any absorption of water or organic substance before it's used, otherwise it must be regenerated. 
All Chemequip molecular sieves can be regenerated by temperature or pressure swing.

Delivery
For small quantity order < 100kg, 10 days after purchased contract is efficient.
For big quantity order > 500kg, 15 days after purchased contract is efficient.
