Polyester film (PET / Mylar-type) is the most common electrical insulation film. Keywords: polyester film, PET film, Mylar film, electrical insulation film.
Gala lists 0.012–0.350 mm and polyester tape with slitting.
First choice for volume; switch to polyimide on hotspots. Industries: motors, cable, electronics, panels, coil shops.
This guide covers uses, naming, PET vs polyimide and supply.

“PET film offers electrical, chemical and thermal resistance with strong mechanical properties.” — Gala Elektrik, About Us
Applications
Slots/phases, cable wrap, laminate cores, electronics barriers. Tension and edge quality matter.
Thickness follows voltage and bend radius.
Protect from moisture; FIFO.
Naming
Mylar is a brand; PET/polyester is the family. State brand requirements clearly.
“Electrical insulation film” may mean PET or polyimide — clarify.
Naming confusion causes delays.
PET vs polyimide
Volume/cost → PET; hotspots → polyimide. Mixed BOMs are normal.
See polyimide film and Filmcutter laminates.
Deciding without a heat map is risky.
Supply
Slitting cuts scrap. TR stock; docs for export.
RFQ: thickness, width, meters, use, country.
Sample → frame order.
