Polyester film for electrical insulation can be very thick or very thin. Today we will talk about the basic characteristics of polyester film for electrical insulation.

The films should have high resistivity and breakdown field strength, and the electronic structure is characterized by a wide band gap. Low dielectric loss is also required for high-frequency insulation.

Let's talk about the classification of polyester film for electrical insulation: Polyester film for electrical insulation is inorganic and organic.

Inorganic insulators are usually called dielectrics, and commonly used silicon oxide, silicon nitride, aluminum oxide, and aluminum nitride.

Common organic polyester films for electrical insulation materials are polyimide, polyethylene, polyvinylidene fluoride, and polytetrafluoroethylene. Polyester film for electrical insulation: both inorganic and organic insulation, generally have the ability to polarize under the action of an external electric field. Polyester film for electrical insulation requires a low dielectric constant to reduce dielectric loss.

Learn to identify polyester film for electrical insulation, and you'll find quality products easily. Of course, it is also important to find the right manufacturer to supply high-quality PET film.
