Development of heating elements based on conductive polymer composites for electrofusion welding of plastics

Conductive polymer composites have been developed based on high‐density polyethylene filled with carbon black (HDPE‐CB), capable of generating heat when an electric voltage is applied. For each voltage value, the composite reached a constant value of equilibrium temperature, which obeyed a quadratic dependence on voltage and a linear dependence on electric power. The possibility of using such composites as heating elements (HE) for electrofusion...
