Membrane/Filter BUSINESS

The PFSA-PTFE strengthening compound membrane is a cation exchange membrane with remarkably improved chemical/physical durability performance through the fusion of Synopex's proprietary PFSA ionomer dispersion manufacturing technology and ePTFE porous support manufacturing technology.

As a core material of MEA that composes the stack of polymer electrolyte fuel cells, PTFE's high physical durability is the basis for thinner thin film, and accordingly, the electrochemical performance characteristics have been significantly improved.

strengthening compound membrane for automobiles that require strong chemical/physical durability are being studied most actively, and are mainly used for water electrolysis, redox flow batteries, and water treatment.

• PTFE: Polytetrafluoroethylene

• High economic efficiency through stable supply and demand of raw materials and optimization
• High ion conductivity of the membrane by maximizing impregnation through dispersion optimization
• High dimensional stability, durability, and mechanical strength through proprietary PTFE manufacturing technology

Synopex is the first developer of the Perfluorinated sulfonic acid ionomer, and the only company which can supply the core raw materials of the strengthening compound membrane with e-PTFE membrane manufacturing technology in Korea.

The self-supply of raw materials made it possible to secure better economic feasibility. Based on the high understanding of the properties of ionomer dispersion and ePTFE, we have selected only the best grade products and have the technology for manufacturing reinforced composite membranes for fuel cells targeting the global market.
