A molecular sieve is a material with tiny, uniform pores that is used to adsorb gases and liquids. Unlike common filters, the molecular sieve operates on a molecular level. It only could adsorb molecules which are small enough to pass through the pores, such as water molecules. Because of this, the molecular sieve is usually used as a desiccant, which can adsorb water up to 22% of its own weight. Molecular sieves often consist of aluminosilicate minerals, clays, zeolites, active carbons, synthetic compounds, etc. that have pores which small molecules can pass through. Usually, a 4 to 8 mesh sieve is ideal for gas phase applications, and a 8 to 12 mesh sieve is perfect for liquid phase applications. The powder forms of the 3A, 4A, 5A and 13X sieves are used in specialized applications. Xiangrun is an experienced molecular sieve manufacturer in China.
