PI film

PI film, also known as polyimide film, is a high-performance polymer material that plays an important role in many fields due to its excellent physical and chemical properties. Here is a detailed introduction:

physical property

PI film is usually yellow and transparent, with excellent high and low temperature resistance, electrical insulation, adhesion, radiation resistance, and dielectric resistance. Its glass transition temperature ranges from 280 ℃ to over 500 ℃, depending on the type of PI used. Within the temperature range of -269 ℃ to 280 ℃, PI film can be used for a long time, and can even withstand temperatures as high as 400 ℃ in a short period of time.

chemical property

The decomposition temperature of PI film generally exceeds 500 ℃, making it one of the known organic polymers with extremely high thermal stability.

application

PI film is particularly suitable as a substrate for flexible printed circuit boards and insulation material in various motor appliances. Other applications include aerospace, biomedical, marine engineering, and automotive manufacturing.
