The mechanism for converting electrical energy into heat for carbon based heating is mainly the collision of charged particles in the electric field. The performance of the heater or heating film is directly affected by the current and intrinsic resistance of the electro thermal materials. Graphene’s very high current density and thermal conductivity guarantees faster temperature responses and uniform distribution, essential for optimum performance to ensure no overheating or hot spots. NexGen covers 95% of the area with its patented graphite and graphene mix. In comparison, on average, FAR Infrared and Wire Mats cover 2% to 4%, Carbon Film 60% and Infra Red Panels 2%.
