In the realm of advanced material science, the control of moisture and volatile compounds is paramount for achieving optimal product performance. NINGBO INNO PHARMCHEM CO.,LTD. proudly presents its high-quality 3A Molecular Sieve Powder, an indispensable solution for critical industrial applications, particularly within the polyurethane sector. This specialized activated zeolite powder is engineered to offer unparalleled moisture scavenging capabilities, directly addressing challenges such as gassing and bubbling that can compromise the integrity and finish of final products.

Our 3A Molecular Sieve Powder, characterized by a precisely controlled pore size of approximately 3 angstroms (0.3 nm), selectively adsorbs water molecules while excluding larger molecules. This unique selectivity is crucial for applications where the removal of moisture is necessary without affecting other essential components of a system. As a finely micronized white powder, it boasts high dispersibility and rapid adsorbability, ensuring seamless integration and immediate action when mixed into various formulations.

One of the primary and most significant applications of our 3A Molecular Sieve Powder is its role in two-component (2K) polyurethane systems. Polyurethane adhesives, coatings, sealants, and mouldings are highly sensitive to moisture contamination. Even trace amounts of water can react with isocyanates, leading to the formation of carbon dioxide (CO2) gas. This unintended reaction results in undesirable gassing and bubbling, causing aesthetic imperfections like pinholes and voids, and more critically, diminishing the structural strength and uniformity of the cured material. By effectively scavenging this inherent moisture, our 3A Molecular Sieve Powder prevents CO2 generation, ensuring a smooth surface finish and enhanced mechanical properties.

Beyond 2K polyurethanes, our activated molecular sieve powder offers protection for 1K-polyurethane storage and is vital for moisture control in polyurea systems and zinc-rich paints, where preventing unwanted reactions and maintaining product stability are critical. Its utility extends to desiccating insulating glass units, metallic pigment paints, and polysulfide and silicone systems. Furthermore, it serves as an excellent carrier for chemicals requiring controlled release, a processing aid in polymer production, and an additive in cosmetics and flame retardants. It also facilitates chemical reactions by removing water as a byproduct and is effective in drying highly polar compounds such as methanol and ethanol, as well as natural gas and unsaturated hydrocarbons like ethylene, propylene, and butadiene.

Choosing the right desiccant is vital for product quality and operational efficiency. Our 3A Molecular Sieve Powder is manufactured under stringent quality control, ensuring consistent performance and reliability. Its attributes, including robust static water adsorption capacity and high mechanical strength, contribute to extended product life and superior results in diverse industrial settings.
