First of all, the high-temperature PI film is made of homophthalic anhydride and diaminodiphenyl ether in a strong polar solvent to form a film, and then it is formed by imamineization. It is a thin film insulation material with good performance; Also known as polyimide film, high temperature PI film has the following advantages!
(1) Excellent heat resistance
(2) Excellent mechanical properties
(3) It has good chemical stability, moisture resistance and heat resistance
(4) Good radiation resistance
(5) Good dielectric properties
Scope of application:
1. High temperature PI film can be used as flexible printed circuit board material (FCCL) and a variety of high temperature motor electrical insulation materials, as well as PI coated silicone / acrylic adhesive, the formation of single or double side high temperature resistant tape for electronic packaging protection, high temperature paint protection, spray masking protection, etc.
2. Lithium battery black self-adhesive edge PI material is mainly used in the hemming of mobile phone cells, the coating of mobile phone cells and others. This material needs to be stored in a dry, clean warehouse, suitable storage temperature: 10 °C-30 °C, storage period of one year, avoid storing with organic solutions, liquids.
3. PI lithium battery heat insulation sheet is surrounded by silicon dioxide aerogel by PI film under rubber-free hot pressing, mainly used in lithium battery packaging thermal buffer and other high temperature environment thermal insulation buffer
