0.075mm PI Film (Polyimide Film)
1. PI films (polyimide casting film)The polyimide casting films of our company are produced by polymerizing and casting pyromellitic dianhydride (PDMA) and 4.4 - diaminodiphenyl ether (4.4 – ODA) to form H-grade insulating film. They have following good properties:1) Good properties of insulation and tensile strength2) 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 property3) Good chemical stability and resistance to corrosion4) Excellent flame retardant property5) Good radio-resistance. After the film being irradiated with r ray of 109 remain its properties unchanged6) Can be mixed with many materials. When mixed with fluorine resin moisture protection and corrosion resistance are greatly improved2．Main Specifications (Standard No ：JB/T2726-1996)3. Main Specifications4．Application:1) Applied to electromagnetic wire, high-temperature cable, motor, electric machine, electric appliance2) Polyimide film tape, electric insulating tape, as base film for FEP films and so on
