PYROLYTIC GRAPHITE PRODUCTS
Pyrolytic graphite is characterized by high density, no pores, easy machining, high anisotropy, high purity, high temperature resistance, low elastic modulus, high thermal conductivity, small thermal expansion coefficient, good chemical stability and other characteristics. It is widely used in:
1. Throat lining for rocket \ missile nozzles
2. Crucible for smelting high purity metal
3. High-power electronic grid
4. Brush for voltage regulator
5. Graphite heating coating for semiconductor industry
6. Atomic absorption tube coating for analyzer
