4A Molecular Sieve Series4A Molecular Sieve Series

4A Zeolite  is white solid powder. A reticular structure, with uniform pore, pore size of 0.42 nm, specific surface area is about 600 m2 / R, insoluble in water and organic solvent, can dissolve in alkali and acid. Heating exceeds 800 ?/SPAN>, recrystallization form white silica shape of structure.

The molecular sieve powder have the effective performances of adsorption and selectivity.We supply verious kind of Molecular sieve,such as type A,X,and Y crystal structure,and it is suitable with application of insulating glass desiccant,refrigerant desiccant.

Huiying Chemical Industry (QuanZhou) Co., Ltd. has been actively involved in development and production of zeolite products for more than 19 years. We continue to provide verious kind of zeolite products for our customers.

The aperture of 4a molecular sieve is 4A that couldn’t adsorb any molecule greater than 4a(including dimethylmethane).4A molecular sieve is one of maximum varieties volume. Mainly use in natural gas, liquid desiccant and H2O, NH3, H2S, CO2, SO2, CO adsorption. Widely use in ethanol dehydration.
