4A(Bead, Pellet) (423979)

Details:

Molecular sieve 4A is made by raw powder, which has zeolite A crystal structure, with selected mineral binder. 4A Molecular sieve has an effective pore opening of 4Å (0.4nm), so molecules which diameter less than 4Å can be adsorbed. Mostly used for dehydration of natural gas.
