The introduction of these small chain segments in the polyethylene framework renders the membrane hydrophilic. • THOMAPOR ® -membranes „RP“ have a low resistivity in alkaline media. They are suited for recovery of sodium hydroxide out of viscose solutions. The support film consists of high-pressure polyethylene (HDPE). The graft type is weakly cationic. • Electrodialysis membranes have always to be kept wet and should be stored in a 3 % NaCl solution in a cool and dark place. Technical specification • Resistivity:
