The surface material of Kellogg electric heating film is a special polyester film, and the ink line in the middle of the film is conductive ink, which is the core part of the electric heating film, equivalent to many parallel resistors, and can generate heat after being electrified. The silver bars on both sides of the electrothermal film are metal current-carrying bars, which are used to connect ink (resistors) and play the role of wires. The main materials of metal current-carrying strips are copper tin plating and silver ink.
Kellogg electric heating film adopts American aerospace patented technology, which is exclusively produced by Kellogg company of the United States with special manufacturing technology and special materials. Kellogg Company of the United States uses advanced computer numerical control technology to manufacture electric heating film, accurately controls the thickness of cured ink on the film, and ensures the uniform and stable surface temperature of the film.
Low-temperature radiant electrothermal film is a translucent polyester film, which can generate heat after being electrified. It is made of conductive special ink and metal current-carrying strip through processing and hot pressing between insulating polyester films. When working, the electrothermal film is used as the heating element, which sends heat into the space in the form of radiation, so that the human body and objects can be warmed first, and its comprehensive effect is better than the traditional convection heating method. The low-temperature radiation electrothermal film system consists of power supply, temperature controller, connector, insulation layer, electrothermal film and decorative layer. The power supply is connected with the electrothermal film through wires to convert electric energy into heat energy. Because the electrothermal film is a pure resistance circuit, its conversion efficiency is high, except for a small part of loss, most of it is converted into heat energy.

The electrothermal film is the core component of the whole system and the heating component of this system. Its base material is PET polyester film, the heating element is conductive ink, with silver paste and conductive metal bus bars as conductive leads, and finally it is compounded by hot pressing. The heating of electrothermal film mainly radiates heat in the form of radiation, which belongs to low temperature radiation. It is transmissive and radiates heat indoors in the form of infrared rays.
(3) Connecting wire, connecting card and insulating cover
The connecting wire supplies power to the electrothermal film and forms a loop for the whole circuit. The connecting card and insulating cover are used to facilitate the connection with the electric heating film to ensure safety.
(4) Temperature controller
Control the whole electric heating film system to ensure the stability of indoor temperature.
Product connection
As shown in figure 1, the electrothermal film is connected to the thermostat through the connecting card, and each group of films is connected in parallel, and finally connected to the thermostat in series through a group of wires. All connectors are sealed in the connector card, and no joint points can appear in the wires.

Installation method of accessories and connecting cards:
▼ The connecting card is installed at one end of the electrothermal film group (the other end is insulated with insulating tape).
▼ Align the center of the connecting card and cover one end of the current-carrying bar. Press in place with your fingers.
▼ Use the flat part of the special crimping pliers to flatten the connecting card onto the electrothermal film.
▼ Each group of electric heating films is connected in parallel, and the insulation of wires and connecting cards is peeled off for 6mm, and then it is.
▼ Insert the link card into the cylindrical tube. (Except for the last group, each connecting card must have two wires to connect with the adjacent membrane group. )
▼ Press the conductor with the cylindrical pressure interface of special crimping pliers, and check whether the connection of the conductor is firm by pulling.
▼ Install the insulating cover, fill the groove of the insulating cover with hot melt adhesive, place the connection card that has been pressed on the electric heating film on the groove of the insulating cover, and press it with your fingers.
