VieTape GP4200 synthetic graphite is an extremely light and flexible material synthesized from polymer precursor through high temperature heat treatment process. Derived from the crystal structure of graphite, VieTape GP4200 graphite features an anisotropic and overall high thermal conductance. It possesses unique functions such as eliminating hot spots, shielding components and reducing skin temperature of electronic devices. It is an ideal heat spreader for thermal management in limited space. VieTape GP4200 can be supplied in rolls or die-cut form and can be laminated with plastics, foams and PSA.
