These thermal pads are made from a carbon-based polymer with nanoparticles; They have a high thermal conductivity of 62.5 W/mk The non-adhesive and flexible carbon thermal padding can be used repeatedly and, unlike pastes, does not dry out The thermal conductive pad meets the expectations of gamers and IT enthusiasts alike, who are primarily looking for a high quality product from Thermal Grizzly The thermal pad material is virtually non-degradable, so its properties are solid and its lifespan almost unlimited (rumored to be up to 15 years) Suitable for CPU cooling, GPU cooling, and any application that requires the use of pads instead of thermally conductive pastes. Carbonaut is an electrical conductor - avoid contact between thermal pad and transistors or transformers
