POLYIMIDE CASTING FILM,Polyimide film

                                                           POLYIMIDE CASTING  FILM

1.    Structure and Property

The polyimide casting film of our company is produced by polymerizing and casting pyromellitic dianhydride and 4.4 diaminodiphenyl ether to form H-grade insulating film. It has following good properties:

1)     good properties of insulation and tensile strength;

2)     good temperature – resistance and used in wide temperature range, between -60℃~+250 for a long period and between –269℃~+400 for a short period without changing in tensile strength or insulating property.

3)     good chemical stability and resistance to corrosion.

4)     excellent flame retardant property

5)  good radio-resistance. After the film being irradiated with r ray of 109 remain its properties unchanged.

6)     can be complexed with many materials, when complexed with fluorine resin moisture protection and corroision resistance are greatly improved.
