High electric conductivity pyrolytic carbon graphite heat spreader sheet paper with pet film
High electric conductivity pyrolytic carbon graphite heat spreader sheet paper with pet film
High electric conductivity graphite sheet, also called artificial graphite sheet, is a new film material made of Polyimide by sintering. Synthetic graphite sheet 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.
