Product  Name:Polyimide film for Polyimide Tubing

Material and Applicable Range: As one of the tape with ground of polyimide film, it is manufactured by means of “doctor-blading process”. Cover glue F46 on single surface or double surfaces; process them after drying and cutting. By virtue of excellent performance, the tape can replace  adhesive tape F46. This tape is applied to act as grade H insulating material of electrical wire lapping. It takes into its shape through melting at 350-380 °C over ten minutes.

I.Technological requirement:
1. Appearance: The tape needs to be dry, smooth with no bubble or impurity, etc. 2.Dimension:
(1)Length: The length of every roll of tape is not less than 1000m and the number of sections is no more than 4.
(2)Width and allowable deviation of the tape is 10mm ±0.5mm, 15mm ±0.5mm, 20mm ±1mm, and 25mm ±1mm. Tape with other width specifications can be offered according to the requirements of customer.
(3)Nominal thickness and allowable deviation: thickness range 0.03mm---0.05mm; allowable deviation is ±0.004 mm; special requirements of customer still can be provided.

Process for producing Polyimide Film

Process:

Resin synthetise—-filter—cast—-imidization—rolling—inspection—-slitting—package

1 Resin synthetise

Synthetise PAA with 3 raw materials of PMDA ODA and DMAC after chemical reaction.

2 Filter
Bubble clearing in bubble clearing pan after filter. Second time filter after bubble is cleared.

3 casting
Resin is casted on the belt through mould. Slicked resin is circled in hot wind in order to solvent evaporation and some imidization. The preliminary dry film (PAA film)  is conveyed to the front peel roll of casting machine and peeled off.

4 Imidization
Imidization process is heat imidization. Film peeled off from cast machine is imidized in imidization oven in high temperature. PAA film is transfromed into PI . In imidization, film is strengthed in CD, then the film is rolled.

5 Dry film temperature and  machine speed.
