molecular sieve 4A
Description:
A kind of alkali metal alumino-silicate,in the sodium form of the Type A crystal structure.It could absorb the molecules which critical diameter is not more than 4 angstroms. The selective adsorption performance of water is higher than any other molecules. It is one of the most used molecular sieve varieties in industry.
