High-purity PTFE (polytetrafluoroethylene) membrane separator discs designed for lithium-air battery research and advanced electrochemical testing.

This hydrophobic microporous PTFE membrane features a nominal pore size of 0.2 µm, offering excellent chemical resistance against acids, alkalis, organic solvents, and aggressive electrolytes. Its high porosity and controlled pore structure make it suitable for oxygen diffusion control and gas-phase electrochemical systems.

Supplied as 47 mm diameter discs, 100 pieces per pack.
