PFSA Kationen Exchange Membrane 20 x 30 cm 30µm
The fumapem is also a fluorinated polymer with sulfonic acid groups, which are responsible for the proton transport. The fumapem, made by fumatech, is in different thicknesses and equivalent weights available. The first number in the part number ( 9 or 10) shows the equivalent weight in 100 g/eq.
The last two numbers show the thickness of the membrane in 1/1000 mm (30 or 50 μm).
