*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
