PET soft electric heating film is printed with conductive carbon ink on the underlying polyester insulation film (stripe-shaped horizontal distribution), copper foil electrodes are placed longitudinally at both ends of the ink strip, and the polyester insulation film is laminated and hot-rolled on the upper layer. The heating element is a carbon ink. This product has high production efficiency, good softness and easy to use. The disadvantage is that the copper foil electrode and the ink strip are easily cracked at a low temperature (less than 80 ° C), and the contact is poor, which causes electric spark. After long-term use, the heating element is easy to age and harden, and it is easy to generate microcracks. Carbon fiber paper hard electric heating plate is obtained by placing conductive carbon fiber paper and copper foil electrodes at both ends between two glass cloth laminates under pressure and heat curing. The heating element is carbon fiber paper. This product is used at a high temperature, the heating element does not age, the life is long, and the resistance is stable. The deficiency is due to the mechanical contact between the conductive carbon fiber paper and the copper foil, which easily leads to poor contact; the texture is hard and cannot be rolled and cut.

In view of the shortcomings in the above problems, Zhejiang Hangzhou Risheng Electric Heating Products Co., Ltd. provides a flexible electric heating sheet with high heating efficiency, reliable structure, safe use, soft texture, convenient and durable. The flexible electric heating sheet includes an upper film layer, an upper insulating layer, an electric heating film, a lower insulating layer and a lower film layer which are sequentially stacked, and the electric heating film is composed of an upper thermal conductive film a, a lower thermal conductive film b, and electric heat sandwiched therebetween. The two ends of the heating wire are respectively connected with the connecting pipe for connecting the external power supply; the upper film layer and the lower film layer are an epoxy film layer, a polyimide layer, a polyamide layer, a polyester layer, and a silicone One of the layers; the upper insulating layer and the lower insulating layer are a glass fiber layer or a mesh non-woven fabric layer. In the flexible electric heating sheet , a black ceramic layer is further wrapped on the outer wall of the electric heating wire.
