Ethanol and Solvent Drying
Selectively removes water while limiting adsorption of larger product molecules.
Industrial Adsorbent Material
3A Molecular Sieve
3A Molecular Sieve: Potassium-exchanged type A zeolite, 3Å pore. Review applications, particle size, storage, samples, and quotation requirements.
Technical Specifications
pore size 3Å
composition Potassium-exchanged type A zeolite
form Spheres or extrudates; powder grades by application
common particle sizes 1.6-2.5 mm and 3-5 mm; confirm current specification
regeneration temperature Process- and grade-dependent; confirm the supplier TDS
Applications
Insulating Glass
Controls moisture in compatible spacer systems to reduce internal condensation risk.
Gas Drying
Removes water from gas streams where a restrictive pore opening is required.
Moisture-Sensitive Formulations
Powder grades may be evaluated in polyurethane and other formulations after compatibility testing.
Advantages
- Selective adsorption of water
- Limits entry of molecules larger than the nominal pore opening
- Available in formed and powder grades for different uses
- Can be regenerated in systems designed for cyclic operation
Limitations
- Not interchangeable with 4A, 5A, or 13X without process validation
- Requires sealed, moisture-resistant storage before use
- Particle size and form must match the equipment or formulation
Frequently Asked Questions
What is the pore size of 3A Molecular Sieve?
The nominal pore opening is 3Å. Adsorption suitability still depends on molecular dimensions, polarity, process conditions, and the selected grade.
What is the regeneration temperature?
Regeneration temperature is Process- and grade-dependent; confirm the supplier TDS. Proper regeneration restores adsorption capacity for multiple cycles.
What standards does it comply with?
ISO-9001, REACH
How should it be stored?
Store in a dry environment before use. Avoid exposure to acidic gases. Keep sealed when not in use to prevent premature moisture adsorption.
