A floor heating bendable, electrically conductive, thermoplastic mat having at least two electrodes arranged along each side edge of the mat. The mat includes a material composition whose volume resistivity increases substantially with an increase of temperature of the material composition below 30°
A floor heating bendable, electrically conductive, thermoplastic mat having at least two electrodes arranged along each side edge of the mat. The mat includes a material composition whose volume resistivity increases substantially with an increase of temperature of the material composition below 30° C. The material composition comprises a semicrystalline polymer and an electrically conductive filler material. The polymer has a crystalline melting point which exceeds a normal working temperature of the mat but is below 99° C. and whose softening temperature (Vicat) is in a range of 45-70° C. The mat is self regulating regarding temperature and power for floor heating.
