4、 The production method of this double-sided aluminum coated polyimide PI film includes two steps:

Firstly, the polyimide resin powder is mixed with inert gas, and then subjected to high-temperature treatment in a hot air flow to uniformly melt and form a uniform thin film. This process requires sufficient temperature and pressure to ensure that there is enough polyimide resin powder in the film. Afterwards, place the film on a press and treat it through vacuum heat treatment or ultraviolet irradiation. This will allow the polyimide resin powder in the film to deposit uniformly on the surface, forming a dense coating.

The double-sided aluminum coated polyimide PI film also has good corrosion resistance and UV radiation resistance. This makes it an ideal choice for devices such as electronic products and instruments. In addition, the material also has lower weight and higher strength, which can effectively reduce the weight of electronic products and equipment such as instruments.

In addition,Double sided aluminum coated polyimidePI film also has good electrical and mechanical stability, and can be used to manufacture precision electronic products, optical instruments, medical equipment, etc.
In summary, the double-sided aluminum coated polyimide PI film with a thickness of 25 microns is a high-performance and high-quality electronic product film material with broad application prospects.
