Product description

Molecular Sieves Molecular sieve is a adsorbent containing tiny pores of a precise and uniform size, and is used as an adsorbent for gases and liquids. Because of their crystalline composition, it will yield virtually water-free products. These empty adsorption cavities allow selective adsorption. Molecules small enough to pass through the pores are absorbed while larger molecules are not. Molecular sieve can absorb water up to 22% of its own weight. Molecular sieve has a high re-activation temperature and moisture locked is not easily return to the ambience. They are usually used in bulk in filtration systems or packaged in sachets for dry packing.

SIZE OF PORE	LIQUID ADSORBED
3A	- Helium Hydrogen - Carbon Monoxide - Ethanol - Methane - Ethylene
4A	- Water - Methanol - Ethanol - Sulfurated hydrogen - Carbon dioxide - Ethylene - Propylene
5A	- Methanol - Ethane - Propane
13X	- All of above - Aromatics - Branched-chain hydrocarbon
