Characteristics

Molecular sieve 4A’s formula is: Na2O Al2O3 2.0SiO2 4.5H2O.

It’s one of the most widely used molecular sieves in industry. It adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene and propylene. Its selective adsorption ability to water is higher than other molecular sieves.

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.
