4A Molecular sieveSpecific Application：
Deep drying of air, natural gas, alkaline, refrigerants and other gases and liquids; Static drying of pharmaceutical packaging, electronic components and perishable objects; The preparation and purification of air etc.
Guangdong Xintao Molecular Sieve type 4A is an alkali alumina silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). Guangdong Xintao type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorb-able molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded.
