Product Description

3A Molecular Sieve: Key Features and Applications

1. Chemical Composition & Structure

Formula:

2/3K₂O⋅1/3Na₂O⋅Al₂O₃⋅2SiO₂⋅9/2H₂O

Uniform pore size: 3 A (0.3 nm), selectively adsorbs H₂O and small polar molecules (e.g., NH₃), while excluding larger molecules (e.g., ethane).
Thermal stability: Regenerable at 350°C; complete moisture release at 650°C.

Major Applications
Industrial DryingDeep dehydration of natural gas, ethylene/propylene, and liquid ethanol (dew point < -70°C).
Prevents ice formation in pipelines and improves fuel purity.
Insulated GlassDesiccant for spacer layers, complying with EN1279 standards (no fogging at -40°C to 70°C).
Electronics & CoatingsMoisture protection for IC packaging.
Additive in resins/coatings (activated powder form) to prevent bubbling.
