This catalog details Molecular Sieves, synthetic crystalline aluminosilicates (Zeolites) offered as beads, pellets, or powder, including 3A, 4A, 5A, 13X, and automotive XH types. These materials utilize a controlled, uniform micro-pore structure for selective adsorption, serving as adsorbents, ion exchange materials, and catalysts. Key technical features include high moisture absorption even at low humidity, a strong crystal structure resistant to pressure and temperature cycling, and full compatibility with automotive refrigerants (POE, PAG). Benefits encompass protecting compressors and expansion valves, extending system lifetime, and enhancing HVAC efficiency, meeting OEM quality for modern low-GWP refrigerants. Applications range from dehydration in industrial gas and automotive lithium-ion batteries to separation, purification, and deodorization.
