Molecular sieves are used for drying gases and liquids and for separating molecules on the basis of their sizes and shapes. When two molecules are equally small and can enter the pores, separation is based on the polarity (charge separation) of the molecule, the more polar molecule being preferentially adsorbed.

MOLECULAR SIEVES 4A X 1.5mm Dose rate: 0.3-5 ltr per ton wash water (0.03-0.5%).

Molecular sieve starts out as powder. The powder is then combined with a binding material. This allows the powder to be rolled into beads.This exchanges about half of the sodium ions in the structure with potassium ions, which changes the effective diameter of the pore openings and creates the 3A molecular sieve.
