TFO-Y-PG Grafit Folie pyrolytisch

TFO-V-PG consists of pure pyrolytic graphite. Due to the synthetic structure it shows highly anisotropic heat spreading conductivities in-plane (x-y-plane) and in through direction (z-direction). Its flexibility allows for a good compliance to the contact surfaces. Thus the total thermal resistance is minimised. Their low densities make them ideal for applications where low weight is required. The very high temperature resistance allows for the use in extreme hot environments. Due to its high flexibility it is very bending-resistant and mechanically stable. It can be used for curved surfaces and corners because its thermal conductivity will remain unchanged in the absence of sharp folds. The film can be configurated with phase change coating on both sides.
