4A Molecular Sieve
A molecular sieve is a material with pores (very small holes) of The diameter of a molecular sieve is measured in ångströms (Å) or nanometres (nm). According to IUPAC notation, microporous materials have pore diameters of less than 2 nm (20 Å) and macroporous materials have pore diameters of greater than 50 nm (500 Å); the mesoporous category thus lies in the middle with pore diameters between 2 and 50 nm (20–500 Å).

Molecular Sieve 4A

Performance:

4A molecular sieve pore size is 4A, can absorb water, methanol, ethanol, hydrogen sulfide, sulfur dioxide, carbon dioxide, ethylene, propylene, can't absorb molecular sieve that diameter greater than 4A(including propane), the water selecting adsorption performance is higher than other molecules. 4A is the largest one of the molecular sieve varieties of industrial usage. 

Use: 

Mainly used for air, gas, alkanes, the depth of the refrigerant gas and liquid dry; Argon gas making and purification, pharmaceutical packaging, electronic components and mutable material static dry; Paint, coating, fuel as dehydrating agent.
