* Characteristics of graphite film:
1.The surface can be combined with other materials such as metal, plastic, self-adhesive, etc. to meet more design functions and
needs.
2. Excellent thermal conductivity: 150~1200W/m.k, 700-1900W M.K, which is better than metal thermal conductivity.
3. Light weight, the specific gravity is only 1.0~1.3, soft and easy to operate.
4. Low thermal resistance, temperature resistance up to 400ºC
5. The graphite heat sink can be smoothly attached to any flat and curved surface, and can be cut in any form according to customer needs
Thermal graphite sheet can be divided into natural graphite sheet and synthetic graphite sheet. As the horizontal heat conduction materials, both have high thermal conductivity, lightweight, flexible and easy to be cut. So we can offer die cut graphite sheet, graphite tape and composite graphite sheet with adhesive on both sides.
Difference between the two kinds of pyrolytic graphite sheets:
1. The natural graphite sheet, also called graphite paper, under the microscope is much rougher than the synthetic graphite sheet. While the synthetic graphite sheet, also known as artificial graphite foil has fewer impurities and higher density than the natural graphite paper.
2. As pyrolytic graphite material, the thermal conductivity of synthetic graphite sheet is 700~1900W/m-K, while that of natural graphite paper is only 150~600W/m-K.
3. Artificial graphite sheet is more complex and expensive than natural flexible graphite sheet, because artificial graphite sheet is produced during high temperature sintering process. The price and effect of natural graphite paper can be accepted and convinced by industry users, so natural graphite sheet has been widely used in various industries like Petrochemical, Refining and Power Generation industries.
