4A Molecular Sieve
Buy 4A Molecular Sieve Now!
4A molecular sieve has a pore size of 4A or 4 angstrom. Any molecule larger than 4A will not be able to be adsorbed. 4 Angstroms are the sodium forms of the Type A crystal structure. The sequence rate of adsorption is argon, krypton, xenon, ammonia, carbon monoxide, C2H4, C2H2, CH3OH, C2H5OH, CH3CN2, CS2, CH3CL, CH3Br, and carbon dioxide.
The advantages of our high quality 4A mole sieve are consistent adsorption speed, and higher contamination resistance, stronger crushing increasing cyclic times which provide an extended product life. 4A Molecular Sieve is primarily for removing moisture from liquefied and gaseous materials.
It has become one of the most reliable desiccants for a variety of applications including:
Moisture removal in PU Plastic or Paint
Natural Gas Drying
Drying Cracked Gas
Static drying of insulating glass units, whether air filled or gas-filled.
Dehydration of highly polar compounds, such as methanol and ethanol.
Dehydration of unsaturated hydrocarbons (e.g. ethylene, propylene, butadien).
4A Molecular Sieve regenerated and reused. To regenerate the sieve you need to remove the adsorbed moisture and other materials. To regenerate 4A Molecular Sieve heat to a temperature of 250â„ƒ to 450â„ƒ.
Keep 4A Molecular Sieve in an air tight container until ready for use to avoid unintended moisture adsorption.
Typical Formula: Na12[(AlO2)12(SiO2)12] • nH2O
