Preguntas frecuentes
What are molecular sieves 4A powder commonly used for?
Molecular sieves 4A powder is primarily used for gas drying, air separation, and purification, as well as in catalytic processes and as a desiccant in packaging.
What is the chemical formula and molecular weight of 4A molecular sieves?
The chemical formula is **AlNaO6Si2** (simplified as Na₂O·Al₂O₃·2SiO₂·4.5H₂O). The molecular weight is not typically provided for zeolites due to their polymeric structure, but the empirical formula reflects its composition.
How should 4A molecular sieves powder be stored?
Store at **ambient temperature** in a sealed, moisture-resistant container to prevent absorption of atmospheric water or contaminants.
What grades or purity levels of 4A molecular sieves are available?
Molekula supplies **technical-grade 4A molecular sieves** optimized for industrial drying and separation applications, meeting standard purity requirements for zeolite-based adsorbents.
Can Molekula supply 4A molecular sieves in bulk quantities?
Yes, we offer **bulk packaging options** for 4A molecular sieves, including drums or custom quantities tailored to your production needs.
What documentation comes with an order of 4A molecular sieves?
Each order includes a **Certificate of Analysis (CoA)**, Material Safety Data Sheet (MSDS), and batch-specific documentation confirming compliance with safety and quality standards.
