Benefits of Graphite Film
Fast Heating Speed
Graphite's low density and modest thermal capacity allow it to heat up quickly, reducing processing times. This is particularly beneficial in industrial settings where efficiency is critical.
High-Temperature Stability
Graphite can withstand extremely high temperatures, making it suitable for applications like vacuum or protective atmosphere environments. For example, a graphite furnace can reach temperatures above 2000°C, which is essential for advanced material processing.
Corrosion Resistance
Graphite is highly resistant to chemical corrosion, making it ideal for melting precious metals and alloys without contamination.
Application of Graphite Film
Consumer Electronics: Flame-Retardant Graphite Film is used for heat dissipation of core chips in laptops, mobile phone motherboards and 5G RF modules, solving the heat dissipation conflict between high power and thin/light casings;
Battery Packs: Used for heat dissipation of battery tabs and internal flame-retardant protection of battery packs, avoiding heat accumulation and delaying risk spread during thermal runaway;
Electronic Control Systems: Adapted to heat dissipation of IGBT modules, meeting the high-temperature working environment of electronic control systems and flame-retardant safety requirements in the cabin, and is one of the core procurement categories in this field.
Onboard Electronics: Used for traction converters and auxiliary power modules of high-speed trains/subways, adapting to complex working conditions of alternating outdoor low temperature and indoor high temperature, complying with rail transit industry fire safety standards (EN 45545-2 R22/H2);
Charging Piles: Adapted to rectifier modules of high-power DC charging piles, solving the dual needs of heat dissipation and flame retardancy under high-power charging and outdoor environments.
