4a Molecular Sieves, Brand Name : THUNDER, CAS No. : 63231-69-6

We are offering 4a molecular sieves.
4a molecular sieve is a kind of alkali aluminosilicate,able to adsorb moleculars with their critical diameter no more than 4Ç».
It can adsorb h2o,nh3,h2s,so2,co2,c2h5oh,c2h6,c2h4,c3h6
and so on.
It is widely used in the drying of gases and liquids,or used in refining and purification of some gases or liquids,such as production of ar.
