Polyester film, or PET film, is an extremely durable and tear-resistant plastic with excellent electrical insulation properties. PET film has an insulation class of B (130°) and is moisture-resistant, making it well-suited for insulating electrical products.
The film is used as insulation in transformers, generators, circuit boards, cabinets, enclosures, batteries, battery-related products, and electric motors.
Polyester film tailored to your needsMultiple applications
Polyamide can withstand high temperatures—up to 150° in air—and is rated according to UL94 VTM-2 and UL746 (105°). The material is flexible and bendable, yet dimensionally stable, making the PET film highly suitable for mechanically demanding applications as well as for foldable insulation boxes.
The polyester film can be die-cut with fold lines to create a box that encloses sensitive products. We also process other electrically insulating materials worth mentioning. These materials are Nomex® and Formex® and, just like polyester film, can be die-cut into foldable insulating parts.
