SNOWPEAK® 4A Molecular Sieve
4A molecular sieve is one of the most consumable molecular sieves used in industry, its selective adsorption of water is higher than any other molecule. SNOWPEAK 4A molecular sieve adsorbs water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene and other molecules with diameters no more than 4 angstroms. Usually used for gas and liquid drying, but also for refining and purification of certain gases or liquids, such as the preparation of argon.

SNOWPEAK® 4A Molecular Sieve Activated Powder
Activated powder desiccant or activated zeolite powder, is obtained by calcining molecular sieve raw powder at high temperature. Beause the raw powder loses most of the moisture during the calcination process, the activated zeolite powder has strong activity and can be directly used in production as an adsorbent with selective adsorption.

SNOWPEAK® 4A Molecular Sieve Raw Powder
Molecular sieve powder or zeolite powder, is the main raw material for the production of molecular sieve. It adopts the hydrothermal synthesis method to react with sodium aluminate, sodium silicate, sodium hydroxide and water at a certain temperature. The molecular sieve raw powder has the characteristic skeleton of molecular sieve.
SNOWPEAK 4A molecular sieve powder or 4A zeolite powder, is mostly used in the production of polymers such as polyurethane, to absorb moisture and other impurities that affect product quality, without changing its own physical and chemical properties. Also used as a selective adsorbent, added in the production process of specific polymers or coatings, to adsorb carbon dioxide, hydrogen sulfide and other gases. Or used as insulating glass desiccant and catalyst carrier.
