PK-reinforced Cation Exchange Membrane,Thickness:75𝜇m

Catalog NumberACMA00062973

CategoryCation Exchange Membranes

Description	This is a PK-reinforced Cation Exchange Membrane (CEM) with low resistance, high selectivity, high mechanical stability, and high stability in a caustic environment. The mechanical reinforcement is composed of PEEK or PK and it has the open mesh style.
Density	9 - 10 mg·cm-2
Application	Diffusion dialysis for caustic solutions.
Storage	Storage for short and medium time scale (hours up to several weeks) may be done in unsealed containers in 0.5 - 2 wt% NaCl solution or comparable neutral pH electrolytes. For storage over a longer time period a sealed container is recommended using afore said electrolyte with biocide to avoid biological fouling.
