FAQ

What is DGK-PVDF DDL30 mainly used for?

DGK-PVDF DDL30 is mainly used for vanadium flow battery bipolar plates, extruded conductive PVDF sheets and flow-channel plate components that require long service life, corrosion resistance and stable conductivity.

Why choose PVDF for vanadium flow battery bipolar plates?

PVDF offers excellent acid and alkali corrosion resistance for aggressive electrolyte environments. DGK-PVDF DDL30 combines that chemical resistance with carbon-plastic conductivity and mechanical strength suitable for stack assembly.

How does it compare with molded flexible graphite carbon-plastic plates?

Compared with molded flexible graphite carbon-plastic plate routes, DGK-PVDF DDL30 is positioned for stronger physical-mechanical performance and extrusion-based manufacturing, which can reduce production cost for sheet and plate preparation.

What process is recommended for DGK-PVDF DDL30?

The grade is intended for extrusion. Sheet thickness, die setting, cooling, channel machining and conductivity retention should be validated together before batch plate production.
