3A molecular sieve is the type A sialic acids potassium salt. 3A molecular Sieve can be used to adsorb molecular that have a diameter of no more than 3A.
About Molecular Sieves 3A
3A molecular sieve is the type A sialic acids potassium salt. 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 petroleum, chemical, and other industries.
