Molecular Sieve

Molecular sieve is a synthetic zeolite that selectively adsorbs and desorbs water molecules and other polar molecules from gases and liquids.

The desiccant is made from a crystalline aluminosilicate with a SiO2:AI2O2 ratio of 2:1 and is also known as zeolite or mol sieve. Different pore sizes, determined by linking AIO4 and SiO4 tetrahedra together, determine the type of Molecular Sieve.

High Absorption Capacity Desiccant

The desiccant comprises a three-dimensional network of alumina and silica tetrahedra, which create a lattice-like structure with uniform micropores. These micropores act like a sieve, selectively trapping and releasing molecules based on size, shape, and polarity.

Molecular sieves have various applications, including reducing humidity levels, dehydrating, and selectively purifying and separating gases and liquids. They can absorb up to 22% of their weight and have customised pore openings that enable them to separate specific molecules.

Molecular sieves are versatile and can be used in filtration systems or sachets to reduce humidity levels. They can withstand temperatures up to 300°C, making them suitable for machinery applications.

Reduce Humidity and Purify Gases

Molecular sieves can be regenerated at high temperatures when exposed to moisture over a long period. To restore their absorbent capacity, heat them to an optimal temperature of 200°C to 350°C.

Molecular sieves with high absorption capacity, mechanical strength, and low attrition loss are available in different forms, including pellets, spheres, and powders, for use in a wide range of applications.
