Overview
Flexible graphite powder is produced from expanded graphite and retains a worm-like, compressible structure. It is used as a filler for gaskets, packing rings, and thermal interface compounds where resilience and chemical stability matter.
Typical carbon content is high; ash and particle size are adjusted to the sealing or compounding process. It withstands high temperature in non-oxidizing conditions and resists most acids and alkalis.
