How to Choose a Material
For insulation
Start with soft graphite felt for flexible lining and rigid graphite felt for boards, cylinders and self-supporting insulation structures.
For structural parts
Review carbon carbon composite when a lightweight high-temperature carbon material is needed for fixtures or load-bearing components.
For electrochemical systems
Use graphite bipolar plate, flow battery felt and carbon paper pages to compare electrical and application requirements.
