Type 3A Molecular Sieve is recommended for drying unsaturated hydrocarbons and highly polar compounds such as methanol and ethanol. The 3A structure is particularly effective in dehydrating the inner space of insulating glass windows as well as refrigerant gases.
Nominal Pore Diameter: 3Å Molecules Excluded: >3Å effective diameter, e.g. ethane Base: Alumina-Silicate Cation: Potassium
