Molecular Sieve Powder( Activated Zeolite Powder)
Molecular Sieve Powders are calcined synthetic zeolite power, after calcination, they lose most of moisture that they contains, so they can be used as adsorbent or desiccant directly in various application.

Molecular sieve powders give the answer to moisture scavenging problems for a wide variety of applications. This adsorbents are synthetic zeolites with a complex alkali metal aluminosilicate structure. This kind of structure contains pore openings of regular and precisely defined size, allowing the adsorption of molecules selectively on the basis of their size and polarity.

They are largely used to remove moisture from polyurethane polymer systems, they deal with moisture problems without causing undue problems with shelf-life viscosity etc. Other types are used as additives for selective adsorption in defined polymer system or coating systems.

In addition, They may be added to adsorb contaminants such as carbon dioxide, hydrogen chloride, etc. from plastic formulations. They can also function as a carrier to release catalysts into certain systems.
