Molecular sieve is a kind of crystallized aluminosilicate .it has the characteristic of even pore diameter and large surface areas, good thermal stability, large capacity of absorption, high intensity.Speical excellent features as selective absorption, It only absorbs the molecules of which the diameter is less than the pore size of the Molecular sieve.

Selective absorption for polar molecules and unsaturated molecules,The bigger polarity and unsaturated ratio, the stronger selective absorption.strong water absorption even in high temperature, large space velocity or low content of water, it has quite a large water absorption capacity.

A&R Molecular sieve has several types of 3A, 4A, 5A,5A small oxy-enrich,13X,13XACS, IG Desiccant, Refrigerant Desiccant according to its use.
