CHEMXIN Modified Molecular Sieve Activated Powder is an advanced aluminosilicate material with a 3D microporous structure, precisely controlled pore size (0.3–0.5 nm), and high specific surface area (800–1000 m²/g). It provides exceptional moisture adsorption, effectively preventing bubble formation in polyurethane synthesis.
In polyurethane production, trace water reacts with isocyanates to generate CO₂, leading to dense bubbles that weaken bonding strength by up to 50% and reduce water resistance by over 40%. CHEMXIN Modified Molecular Sieve Activated powder eliminates this risk, ensuring smooth surfaces, strong adhesion, and long-term durability.
Traditional activated powders, due to high alkalinity, often interfere with polyurethane reactions. CHEMXIN’s modified formulation overcomes this barrier, making it fully compatible with international polyurethane systems and a direct alternative to Arkema NK30AP.
By replacing imported products with CHEMXIN’s Modified Molecular Sieve Activated Powder, manufacturers can cut raw material costs and enhance competitiveness while maintaining world-class quality.
Proven Applications:
Automotive Sealants: Bubble defects reduced from 12% to 0.5%, adhesion improved by 25%.
Electronic Potting Compounds: Dielectric stability enhanced by 18%, water absorption lowered to 0.03%/year.
Metal Coatings: Moisture kept below 0.1%, storage stability significantly extended.
CHEMXIN delivers reliable, high-performance solutions for polyurethane, electronics, and coatings industries, offering both quality improvement and cost savings.
