Graphene composite material is a thermally conductive material composed of graphene and polymer materials. It has the same heat conduction and heat dissipation effect as aluminum. It can quickly export the heat of the heat source and radiate it to the external medium. It can replace aluminum for various heat dissipation. sheet, radiator. It is light in weight, excellent in flame retardancy, heat resistance, and weather resistance, and has low material thermal expansion coefficient and molding shrinkage rate. It is suitable for LED, electronic and electrical, automotive thermal management and other fields.
