4A molecular sieve is the sodium form of the Type A crystal structure. The pore size of 4A molecular sieve is 4A(angstrom). It is mainly used to absorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, does not absorb any larger molecular than 4A, and oftern used as desiccant in many insdustriels.
Typical Chemical Formula: NaO. Al2O3. 2 SiO2. 4.5H2O
