The pore size of 3A molecular sieve is 3 Å . It does not absorb any molecular larger than 3 Å. It is an alkali metal alumino-silicate, the potassium form of the type A crystal structure.

3 Angstrom, is obtained when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions. Will absorb, in sequence of adsorption rate, helium, neon, nitrogen and water.

According to the industrial application specialties, we endue our products with the characters of higher absorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantages have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery, polymerization for cracked gases, ethylene, propylene and any other non-acidic gases or liquids in petroleum and chemical industrials.
Molecular Sieve 5A is mainly used to remove moisture and can be applied to liquefied and gaseous materials on the whole. The main uses are as follows.
1) Drying of refrigerants (e.g. R22, R134a etc)
2) Removing moisture in paint and PU Plastic
3) Drying of natural gas
4) Cracked Gas Drying.
5) Static dehydration of insulating glass units, whether air filled or gas-filled.
6) Drying of highly polar compounds, such as methanol and ethanol.
7) Drying of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien).
8) Drying of olefins drying, ethanol, etc. 9)Dehydration of many kinds of liquids (say ethanol) air, refrigerant , natural gas or methane , cracked gas, ethylene, ethyne, propylene or butadiene . Formula : 0.4K2O·0.6Na2O·Al2O3·2.0SiO2·4.5H2O

Regeneration Molecular Sieve 5A can be revived for reuse and the required factors for revival are temperature and pressure. To remove the adsorbed moisture and other materials, the revival condition shall be set up considering the features of target material and processing environment. The general revival temperature of Molecular Sieve 3A is about 250°C and it should not surpass 300°C at maximum. Attention: Do not unpack the goods until using, avoid of exposure in air for a long time.Should be stuffed as rapid as possible at filling.
