Grade: Pyrolytic Graphite
Formula: C
Form: Foil/Film/Sheet
Material: Carbon
CAS Number: 7440-44-0
Commodity: Metals
Purity:
99.99%
Pyrolytic Graphite Carbon Foil is a highly ordered monocrystalline graphite foil material produced by Goodfellow. With 17 variations available, it exhibits excellent thermal and electrical conductivity properties. Pyrolytic Graphite Carbon Foil is ideal for applications requiring uniform thickness and flatness such as diffusion barriers, optical reflectors and x-ray monochromators. The high purity and anisotropic nature of this carbon foil make it useful across scientific research and industrial fabrication processes.
