Detailed Introduction of Chloro Alkali Membrane DF2801

DF2801 High Current Density Membrane

Membranes with sacrificial thread channels, with low cell voltage, for 30-34% NaOH

production, suitable for high current density cells. DF2801 membrane has better tolerance for

impurities in feeding brine.
