*Characteristics

The pore size of 4A Molecular Sieve is 4A. It adsorbs water, methanol, ethanol, hydrogen

sulfide, sulfur dioxide, carbon dioxide, ethylene and propylene. It does not adsorb any

molecule with diameter more than 4A(including propane). It’s selective adsorbability to water

is higher than that of any other molecule. It is one of the most widely used molecular sieves in

industry. Molecular formula: Na2O Al2O3 2.0SiO2 4.5H2O

* Application

Deep drying of gases and liquids such as air, natural gas, alkanes and refrigerants

Production and Purification of Argon

Static Drying of Pharmaceutical Packaging, Electronic Components and Perishable Substances

Use as dehydrating agent in paint, fuel and coatings
