  • Description
  • Specification

4A Molecular Sieve

Xintao 4A Molecular Sieve, has an effective pore opening of 4angstroms(0.4nm). 

 It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.

 It is non-toxic, safe and reliable to human body, and has no adverse effects on ecosystem.

Chemical Molecular Formula:

Na2O·Al2O3·2SiO2·4.5H2O.   (SiO2 : Al2O3 ≈2).

Typical Application:

a) Deep drying of air, natural gas, alkaline, refrigerants and other gases and liquids.

b) Static drying of pharmaceutical packaging, electronic components and perishable objects.

c) The preparation and purification of Air.

d) As a dehydrating agent in paint and fuel.

Warranty:

By National Standard HG/T 2524-2010.

Free consultation during the warranty period.
