1. Synthetic graphite sheet
Synthetic graphite sheet, also called artificial graphite sheet, is a new film material made of Polyimide by sintering.
Synthetic graphite is available with an adhesive backing on one side, which can significantly improve the thermal resistance. A wide range of die-cut shapes & components are manufactured to customer specifications on request.
