TFO-S-CB
CONTACT 
TFO-S-CB consists of more than 98% pure natural graphite. Due to the flake-like shape they show anisotropic thermal conductivities in-plane (x-y-plane) and in through direction (z-direction). Their softness allows for a good compliance to the contact surfaces. Thus the total thermal resistance is minimised. Their low densities compared to copper (15%) or aluminium (50%) make them ideal for applications where low weight is required. The very high temperature resistance allows for the use in extreme hot environments.
