Molecular Sieve Powder works through a process called adsorption, which is the ability of the material to attract and hold gas or liquid molecules within its pores. The pores in the powder are precisely sized to selectively adsorb certain molecules while allowing others to pass through, based on their size and polarity. Molecular Sieve Powder is commonly used in gas drying, air separation, and purification processes. It can also be used in the separation and purification of chemicals, such as in the production of fuels and plastics.
