FAQ
What is DGK-PP DDL28 mainly used for?
DGK-PP DDL28 is intended for flow battery bipolar plates, conductive sheets, flow-channel plates and related battery-stack components that need a PP-based carbon-plastic material with high conductivity and workable mechanical strength.
What conductivity level can this bipolar plate PP material reach?
The typical conductivity range is 25-28 S/cm, with resistance around 0.4-0.5 Ω. Final values should be confirmed on the customer plate thickness, pressing condition and flow-channel design.
Which processing methods are recommended for DGK-PP DDL28?
It is developed for extrusion and open-roll milling / open mill processing. During sheet extrusion or plate forming, the conductive network should be kept stable by avoiding unnecessary overheating and excessive shear. Customers usually validate screw temperature, die gap, cooling rate and plate thickness together with conductivity.
Can DEYU adjust the formula for different battery plate designs?
Yes. DEYU can tune conductivity, sheet processability, strength and surface finish according to plate thickness, flow-channel geometry, assembly compression and stack contact-resistance targets, instead of only supplying a general catalog grade.
