The PTC material layer includes a polymer matrix, a conductive filler, and a titanium-containing dielectric filler. The polymer matrix has a fluoropolymer. The titanium-containing dielectric filler has a compound represented by a general formula of MTiO3, wherein the M represents transition metal or alkaline earth metal. The total volume of the PTC material layer is calculated as 100%, and the titanium-containing dielectric filler accounts to for 5-15% by volume of the PTC material layer.

摘要： A PTC heating element and an electric heating device containing such a PTC heating element are disclosed. The PTC heating element comprises two insulating layers with a metallic coating provided on one side and a PTC element arranged therebetween which is provided on oppositely disposed main side surfaces with a respective metallization which is electrically conductively connected to the coating of one of the insulating layers. The metallization provided on one of the main side surfaces is assigned only to one potential for energizing the PTC element. The metallization provided on the other main side surface is assigned to only the other potential for energizing the PTC element. The metallization of the one main side surface of the PTC element and the metallization of the other main side surface of the PTC element are formed in such a way that the current path (P) through the PTC element is extended relative to the thickness (D) of the PTC element.
