Thermal Conductived Grafoil
High Thermal Conductived Grafoil, or ultrathin flexible graphite paper, well know by Heat-dissipating graphite film is a very thin GTS, heat-conducting material with comprehensive properties, also known as thermally conductive graphite film, thermally conductive graphite sheet, graphite heat sink, etc., which provides the possibility for the thinner development of electronic products.
A Ultrathin Graphite Film
Flexible large-area graphene films of 30-100 nm-thickness with high thermal conductived .
The heat-dissipating graphite film has good reworkability. It can be compounded or glued with other film materials such as PET according to the application. This material is flexible, can be cut and punched into any shape, and can be bent multiple times; it is suitable for point heat sources The rapid heat conduction converted into a surface heat source has high thermal conductivity and is made of a highly oriented graphite polymer film. In addition to traditional methods, heat-dissipating graphite film is an ideal material to provide heat dissipation management/power device heat dissipation in a limited area or to provide auxiliary power device heat dissipation.
