Description:
3A Molecular Sieve is the potassium form of the type A crystal structure. It has an effective pore opening of about 3 angstroms(0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers.

Chemical Molecular Formula:
0.4K2O0.6Na2OAl2O32SiO24.5H2O. (SiO2 : Al2O3 2).
