Process for producing Polyimide Film


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.

How Customer Using Polyimide Film Tape?

I used it with my new ’hot air’ rework station for SMT electronics.
Kept me from crisping parts that I was not working on.


How Customer Using Polyimide Film Tape?

I used the tape as insulation over the motor, it was easy to use and the tape stuck well.

How Customer Using Polyimide Film Tape

I do a lot of work on laptops, computers, and various other electronics. If you need to tape down cables inside a computer, than you simply need this tape.


How Customer Using Polyimide Film Tape?

Using it for a 3D printer and it is thin

How Customer Using Polyimide Film Tape

I bought this tape for my 3d printer and it’s pretty good. It does smell pretty bad when it gets hot which didn’t happen with my old polyimide tape so I’m sort of suspicious about the quality.


How Customer Using Polyimide Film Tape?

I’m using this on top of my heated plate for a 3D printer. ABS sticks to it very well with a bed temperature of 70C.

How Customer Using Polyimide Film Tape?

It is heat resistant, and will never degrade, so you never have to worry about sticky residue on your circuit boards. The tape is strong, yet peels off easily, making for the perfect tape in electronics. There is no substitute for polyimide tape, and if you  like me and do a lot of electronics work, than this tape is a ‘must-have’.


How Customer Using Polyimide Film Tape?

This tape is awesome. One of the reasons I got it was to cover the glass on my print-bed to print on with my 3D printer. I have had the same layer of tape on it for months and it works great.


How Customer Using Polyimide Film Tape?

This stuff does work. If you need a durable, high temperature tape, this is it.

Just what I need for repairing on our 3D printer. Holding wires, patching splits in the print surface.

How Customer Using Polyimide Film Tape?

I have been looking for a small yet durable tape to use on my project where I am soldering 60+ surface mount components. This roll of tape has been a life saver when it comes to holding down parts safely, and allowing me to properly solder in all of the connections. There is more than enough tape on the roll to get through any project, and the size is perfect when dealing with 32 pin chips. Holds up to heat quite well (iron temp at 300*F), sticks strong, peels off easy. If you are working on a project like me with a lot of surface mount parts, order a bunch of these rolls, they are invaluable!

Not just a pretty amber colored film

Polyimide (PI) film not only can fully meet any general requirements of a wide variety of industrial applications, but it also possess the unique characteristics of high tensile strength, high-wear tolerance, high-temperature tolerance, and anti-corrosion.  PI completely meets the industrial design requirement of modern consumer's electronics, while at the same time, has always been a standard electrical insulation material for decades. It is the high temperature insulation material properties that enable PI film to have absolute competitive advantage over all others.


Polyimide, abbreviated as PI, is a polymer material with imide group. The reaction mechanism involves the addition of diamines and dianhydrides to form polyamic acid, abbreviated as PAA, and then react into polyimide after high temperature, imidization and dehydration.


Because of the excellent thermal, mechanical and chemical properties, PI is always the best choice when specifying high performance polymer materials, especially for applications in electronic and integrated circuit industries that have strict materials specification. PI is in the position of key materials, such as high temperature tape, IC passivation coating, LCD alignment layer, and insulated materials, etc.


Striving to be the best supplier of high performance polymeric films, We continually strengthen its techniques on research, development and production, persistently producing high value-added product while building up strategic alliance with related industries and individual companies outstanding in their respective fields. We will reinforce its logistics and distribution system that focus on the global market to keep the latest market status for achieving just-in-time supplies and fast after-sales service aiming at being an international partner, not just a domestic vendor.
