Thermal conductive graphite material is divided into natural graphite sheet and synthetic graphite sheet. Maybe you will think that there is no special difference between the two kinds of graphite sheet products. It would be a big mistake to think so. Next, we will understand the basic differences between natural graphite sheet and synthetic graphite sheet from several aspects.
1. Color difference
It can be seen that the color of natural graphite sheet is darker, while the color of artificial graphite sheet is light white.

2. Graphite density
The natural graphite sheet under the microscope is much rougher than the artificial graphite sheet. Artificial graphite sheets have fewer impurities and higher density than natural graphite sheets. The thermal conductivity of synthetic graphite is 700 ~ 1500w, while that of natural graphite is only 300 ~ 700w.
The thermal conductivity of natural graphite is about 300-700W/m.K
The thermal conductivity of synthetic graphite is about 700-1500W/m.K
3. Price difference
Artificial graphite sheet: Artificial graphite is more complex and expensive than natural graphite, so the demand of general industry products will not accept its cost.
Natural graphite sheet: The price and effect of natural graphite sheet can be accepted and convinced by industry users, so natural graphite sheet has been widely used in various industries.
Artificial graphite sheet and natural graphite sheet are both materials of horizontal heat conduction. Because sintering of artificial graphite sheet requires high temperature and higher temporary cost compared with natural graphite sheet, natural graphite sheet has more advantages in cost and price, and synthetic graphite sheet has more advantages in heat conduction.
DSN, as a professional supplier of graphite thermal conductive and heat dissipating materials, is committed to the production and manufacture of professional pyrolytic graphite sheets, including natural graphite sheets and synthetic graphite sheets, and has been making unremitting efforts.
