The raw material of natural graphite film comes from natural graphite ore, which is totally different from synthetic graphite.
Its process is that natural graphite ore is crushed, screened, purified, floated, sintered and calendered,
with a carbon content of 99~99.6%.
The thermal conductivity of natural graphite film ranges from 150 W/m-K~500 W/m-K, with 1.0~1.7g/cm3 density.
Because of its low cost, natural graphite film is widely used in heat dissipation, such as notebook,
floor heating, liquid crystal television, ship, power battery, lithium battery, new energy automobile, etc.
