What material is pi heating film?

PI electrothermal film is a kind of electrothermal material made of polyimide (PI). Polyimide is a kind of high-performance engineering plastic, which has excellent properties such as high temperature resistance, corrosion resistance and radiation resistance, and is widely used in high temperature, high pressure and high precision industrial applications.

PI heating film is a structure that polyimide material is processed into a thin film, and a layer of metal circuit is electroplated on its surface to form a resistor, so that heat can be generated when electricity is applied. Due to the excellent performance of PI material, PI heating film has the advantages of fast heating speed, uniform heating, good flexibility and strong pressure resistance, so it is widely used in industrial heating, electric heating equipment, medical equipment, automotive electronics and other fields.

Besides PI materials, other materials can also be made into heating films, such as polyamide, polyester, polyethylene and PTC materials. PI heating film is considered as one of the best heating film materials at present because of its unique performance advantages.
