Product  Name:Polyimide Casting Film

 

Material and Applicable Range: The polyimide film is produced, by means of “doctor-blading process”, by the raw materials of pyromellitic dianhydride and diaminodiphenyl ether synthetic resin. It can resist high temperature, the radiation as well as possesses excellent dielectric performance and physical performance. It is applied to motor Grade H, electric appliance insulation, and those special electric insulating materials for other purposes.

 

I. Technological requirement:
1. Appearance: Provided in rolls, the film surface is smooth, bright and clean. To get perfect effect, the surface must have no folding, tearing, particulate, air bubble, pinhole and any external impurity. The edges of film should be orderly and have no breakage. 

2. Dimension
1) Thickness and allowable deviation: The referenced thickness is as followed in Table One. Products with other thickness can be produced according to the requirements of customers.
