Activated molecular sieve powder is a white powder, which is formed after deep processing and activation of artificially synthesized molecular sieve raw powder.

Activated molecular sieve powder is obtained by roasting molecular sieve raw powder at high temperature. Because the molecular sieve raw powder loses most of its moisture during the high-temperature roasting process, the activated zeolite powder has strong activity and can be directly used in production as an adsorbent with selective adsorption.

Activated molecular sieve powder is widely used in the production of polymers such as polyurethane. It can absorb impurities such as moisture that affect product quality without changing the physical and chemical properties of the product itself. It can also be added as a selective adsorbent in the production process of specific polymers or coatings to absorb CO2, H2S and other gases produced during the production process. Some powdered molecular sieves can also be used as desiccants in insulating glass composite strips, or as catalyst carriers.

Molecular sieve powder and material mixed dispersion adsorption, is an amorphous desiccant. It can absorb impurities such as moisture that affect product quality without changing the physical and chemical properties of the product itself.

Xintao Molecular Sieve Activated Powder is widely used in two-component polyurethane systems. It can effectively absorb moisture in the polyurethane system, thereby preventing isocyanate and water from reacting to produce bubbles and improving the quality of polyurethane products.  

>Moisture is often a problem in the production of polyurethane products. If the moisture cannot be effectively removed, the moisture will react with the isocyanate component to generate carbon dioxide as follows.

RNCO+H2O→RNH2+CO2

>Activated powder is an efficient and non-toxic desiccant, which can effectively absorb moisture in one-component and two-component polyurethane systems, thereby preventing the reaction between isocyanate and water to generate bubbles.

>At the same time, molecular sieve activation powder can mix polyol and isocyanate well. Molecular sieve activating powder has good dispersibility and can effectively prolong the service life of polyurethane products.
