The difference between natural graphite flakes and synthetic graphite flakes
Natural graphite sheet
The value of natural graphite and the relationship between its purity and particle size. Natural artificial graphite sheet has high thermal conductivity, easy construction, flexibility and compressibility. The applicable temperature range is -40~400℃ (under inert environment). No gas and liquid permeability, graphite sheet is not aging and embrittlement, suitable for most chemical media, thermal conductive graphite sheet is widely used, such as: integrated circuits, high-power density electronic devices, computers, cutting-edge electronic instruments, etc. The computer and electronic industries have good market prospects.
The price of natural graphite flakes and its effects can be accepted and convinced by industry users, so natural graphite flakes have been widely used in various industries.
Synthetic graphite sheet
Definition and characteristics
Synthetic graphite sheet, also called artificial graphite sheet, is a brand-new heat dissipation material. It uses advanced carbonization and graphitization processes to produce a thermally conductive film with a unique lattice orientation through high temperature sintering at 3000 ℃. Mainly dissipate heat uniformly in two directions, and the lamella structure can be well adapted to any surface.
1. Thin materials, suitable for products with thin products and small gaps;
2. High temperature resistance, high strength, stable chemical performance;
3. Low thermal resistance, light weight, excellent electrical conductivity, and electromagnetic shielding effect;
4. High thermal conductivity (good horizontal heat dissipation effect), the graphite heat sink can be smoothly attached to any flat and curved surfaces (the application needs to pay attention to short circuit and ESD problems).
