Pyrolytic Graphite Products
Pyrolytic graphite (PG) is a new carbon material produced by pyrolysis and deposition of hydrocarbon gases at high temperature.
- High purity(99.99%)
- Impermeability
- High crystallographic orientation
- Corrosion resistance
- Anisotropy of thermal, electrical, magnetic, and mechanical properties
About Pyrolytic Graphite
The normal thickness of pyrolytic graphite is 2-5mm, and graphite is used as a matrix for vapor deposition at a temperature of 1950-2000 degrees Celsius. Finally, different coefficient of thermal expansion is used for demudding. And 0.07-0.05mm is too thin, can only be the coating, even the thickness of the coating is about 0.1mm.
It is widely used in aerospace, electronic devices, semiconductors, chemical medicine, biomedicine and other fields.
