PTFE-reinforced Extruded PFSA Cation Exchange Membrane

Catalog Number	ACMA00062978
Description	The membrane is an extruded per-fluorinated sulfonic acid cation exchange membrane - PTFE reinforced. This membrane has low electrical resistance, high selectivity, very high mechanical stability, very high stability in basic and acidic environments.
Application	Electrolysis applications and electrochemical processes requiring cation exchange membranes with high oxidative stability and highly resistant to chlorine
Storage	Storage in dry conditions is preferred. If the membrane is pre-treated already, you should store in unsealed containers in 3-5 wt% NaCl solution or comparable neutral pH electrolytes.
Backing Foil	None
Color Form	White
Delivery Form	Wet
Dimensional Swelling	9 - 11 %
Electrical Conductivity	> 55 mS cm-1
