Graphite properties

1. High temperature resistance: Graphite has a melting point of 3850+50℃ and a boiling point of 4250℃. Even after being burned by an ultra-high temperature electric arc, the weight loss is very small.

2. High strength: The strength of graphite increases with temperature; at 2000℃, the strength of graphite nearly doubles.

3. Thermal conductivity: It decreases as temperature increases; in fact, at extremely high temperatures, graphite can become an insulator.

4. Chemical stability: Graphite exhibits good chemical stability at room temperature, resisting corrosion from acids, alkalis, and organic solvents.

5. Unique structure: Graphite is uniformly dispersed in polystyrene, forming a mirror-like surface, which has excellent heat radiation reflection effect;

6. Good thermal stability: It can resist drastic temperature changes such as rapid heating and cooling.
