About Molecular Sieves 3A

The type A sialic acids potassium salts are 3A molecular sieve. 3A molecular sieve has the ability to adsorb molecular that have a diameter of no more than 3A. It is often used for drying unsaturated hydrocarbons gas such as ethylene and propylene. It is also used for the drying of polar liquids, such as ethanol, propylene, butadiene, and so on. It is the preferred choice for deep drying and refining as well as polymerization of liquids and gas in the petroleum and chemical industries.
