Kapton tape is a polyimide-film-based, high-temperature electrical insulation tape with adhesive. Coil shops, transformer OEMs, busbar assemblers, electronics lines, EV battery packs and aerospace harnesses use it for dielectric separation and mechanical hold. Wrong thickness or adhesive class raises thermal aging and failure risk.
Gala Elektrik supplies polyimide Kapton tape and polyimide film from Istanbul with precision slitting. Priority markets: Türkiye, then CIS/Balkans, then selected EU/GCC RFQs.
Kapton® is a DuPont trademark; many RFQs specify generic polyimide adhesive tape. Global references include DuPont, Nitto, 3M and Tesa. OEMs should weight lot traceability, thermal class and converting lead time as heavily as brand.
This guide covers applications, selection criteria, film-vs-tape differences and RFQ structure. Catalog: products · contact.

“As a company open to innovation, we strive to deliver quality products, fair pricing and on-time delivery.” — Gala Elektrik, About Us
Where Kapton tape is used and which industries buy it
Motor/generator phase and lead insulation, transformer exits, busbar edges, EV cell/busbar points, electronics/medical processes, defense/aerospace harnesses.
Türkiye clusters first; CIS and Balkans next; Poland, Germany, Czechia, Hungary, KSA, UAE, Qatar as second wave.
Kapton tape is one BOM element beside PET film, NMN/DMD and glass tapes.
Selection: thickness, adhesive, thermal class, slitting
Thickness, adhesive (silicone/acrylic), thermal class, slit width, chemical compatibility and traceability must be set together.
Checklist: continuous/peak temperature, voltage, thickness-width, adhesive, chemicals, meters, destination.
Common errors: confusing PET with polyimide, quoting without dimensions, skipping converting needs.
Kapton film vs tape and complementary materials
Film for slot/phase; tape for termination/holding. PET for bulk area; polyimide for hotspots. Filmcutter NMN/DMD for ground wall; sleeves for leads.
Sample → process trial → annual frame is the safe path.

Supply, pricing and RFQ
Price drivers: thickness, width, adhesive, volume, stock vs import, destination.
Flow: RFQ → stock/import → slit approval → ship. TCO includes scrap and delay risk.

Frequently asked questions
What is Kapton tape?
A polyimide-film-based high-temperature adhesive electrical insulation tape.
Is it the same as polyimide film?
No. Film is typically non-adhesive for slots; tape is adhesive for termination.
What temperature can it take?
Depends on film+adhesive; select from the thermal profile.
Which industries use it?
Transformers, motors, busbar/switchgear, EV/battery, defense, aerospace, medical, electronics, cable.
Can you slit it?
Yes — Gala slits to customer widths.
Silicone or acrylic adhesive?
Silicone for high heat/removability; acrylic for some process/cost cases — validate by trial.
When instead of PET tape?
When higher temperature or tougher dielectric/chemical duty is required.
What belongs in an RFQ?
Thickness, width, meters, class, adhesive, date, country.
Do you export?
Türkiye-first supply plus CIS/Balkan and selected EU/GCC RFQs.
Global references?
DuPont, Nitto, 3M, Tesa — continuity of spec and schedule matters most.
