Molecular Sieve Beads Type 4A This bag contains both blue moisture indicating molecular sieve and also normal molecular sieve. The blue molecular sieve is a sodium alumina silicate molecular sieve impregnated with an inorganic metal salt moisture indicator. The desiccant will perform as a 4a molecular sieve plus with the additional ability to visually determine when the molecular sieve reaches saturation. When active, the molecular sieve beads are blue, as the beads reach saturation the color changes to beige indicating that the molecular sieve has reached equilibrium capacity and is in need of replacement. While the white molecular sieve is an alkali alumino-silicate in the spherical form. It is the sodium form of the Type A crystal structure with an effective pore opening of approximately 4A. It will adsorb molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Aromatics and branched chain hydrocarbons will not be absorbed. Key Features: Natural Gas Drying The desiccant is known to act as a molecular sieve with the bonus ability to tell visually when the molecular sieve achieves saturation A sodium alumina silicate molecular sieve with inorganic metal salt moisture indicator Dehydration of highly polar compounds, such as methanol and ethanol More efficient than older silica gel and alumina desiccants Crystalline composition Ease of Use Molecular Sieve 4A Technical Data Sheet Molecular Sieve 4A Safety Data Sheet Specifications: Type: 4A Bead Size: 4mm Includes Blue moisture indicating beads Nominal Pore Opening: 4 Angstroms Equilibrium Water Capacity @ 25degC: >= 22% Weight Heat of Adsorption: 1800 BTU/lb of H2O Note: 20lb size comes as set of 2x 10lb containers.
