The electrothermal?film is divided into high temperature and low temperature electric heating film. High temperature electrothermal?film is generally used in electronic, military sector and so on. The low temperature electrothermal?film is a half transparent polyester film which can be heated by electricity, processed with conductive printing ink, a metal carrier flow strip, and a hot press in the insulating polyester film room. electrothermal?film functions as heating element when working, sening heat into space in the form of radiation, so that the human body and other objects will be warmed up. Its integrated effect is better than the traditional convection heating mode. The low temperature radiation electrothermal film is composed of a power supply, a temperature controller, a connecting piece, an insulating layer, an electric heating film and a facing layer. The power supply is connected with an electric heating film through a conducting wire, converting electric energy into heat energy. Because the electric heating film is a pure resistance circuit, so its conversion efficiency is high, its most energy is converted into heat energy except for a little loss.
The electrothermal film is a electric heating element directly that converts electrical energy to heat the heating element, and it is one member in the heated product like the electric heating tube, electric heating rod, electric heating plate, electric heater, electric cooker, induction cooker and so on. But the difference is that the electric heating film in China is still a relatively new product categories, whose application history is only a short span of ten years, so few people konw about the application of electrothermal?film widely. So it is difficult to look up the definition of electrothermal?film in textbook and dictionary;. The domestic and foreign textbooks and dictionaries are very difficult to find the exact definition of electrothermal film, The definition of electrothermal film in China is based on promotional materials of electrothermal?film, mainly include electrothermal?film printed by ink, such as: Electrothermal?film is a kind of half-transparent polyester film that can heat after electrified; processed and hot-pressed with electrified special ink and metal carrier in translucent polyester film made from special conductive ink, the metal carrier asamen processing, hot pressing in insulating polyester film room. Former Ministry of construction named its project report for standard of construction industry as Low temperature radiation polyester electrothermal film; Obviously, it was refering to carbon based printing ink electric heating film. The name was later changed into "low temperature radiation polyester electric heating film". In recent years, with the application of all kinds of electric heating film technology in large-scale production and market, people gradually understand various types of electric heating film. How to accurately define electrothermal?film has become one of the widespread concern and discussion in the industry.
Electrothermal film heating system differs from dot mode heating system represented by radiator, air conditioning, heating radiator represented by some heating systems, streamlined heating system represented by heating cable, and LC supply heating high-tech products designed by aerospace flight technology The electrothermal?film is divided into high temperature and low temperature electric heating film. High temperature electrothermal?film is generally used in electronic, military sector and so on. The low temperature electrothermal?film is a half transparent polyester film which can be heated by electricity, processed with conductive printing ink, a metal carrier flow strip, and a hot press in the insulating polyester film room. Electrothermal?film functions as heating element when working, sening heat into space in the form of radiation, so that the human body and other objects will be warmed up.

The low temperature radiation electrothermal film is composed of a power supply, a temperature controller, a connecting piece, an insulating layer, an electric heating film and a facing layer. The power supply is connected with an electric heating film through a conducting wire, converting electric energy into heat energy. Because the electric heating film is a pure resistance circuit, so its conversion efficiency is high, its most energy is converted into heat energy except for a little loss. Electrothermal?film can not be directly used for floor radiant heating, it requires additional patent PVC vacuum envelope before it can be used in floor heating to ensure the use of effects and life.
