2. Synthetic graphite sheet:
Synthetic graphite sheet, also called artificial graphite sheet, is a new film material made of Polyimide by sintering.
Synthetic graphite is a material consisting of graphitic carbon which has been obtained by graphitizing of non-graphitic carbon, by CVD from hydrocarbons at temperatures above 2500 K, by decomposition of thermally unstable carbides or by crystallizing from metal melts supersaturated with carbon.

Features of synthetic graphite sheet:

• Excellent thermal conductivity: up to 1950 W/m•K (2 to 5 times as high as copper, 3 to 8 time as high as aluminum)
• Lightweight: Specific gravity: 1.9 to 2.1 g/cm3
• Flexible and easy to be cut. (Withstands repeated bending)
• Low thermal resistance
• Low heat resistance with flexible graphite sheet
• Low repulsion and easy to keep the product's shape after attaching
• RoHS, REACH compliant
