Polyester Film PET (Mylar)
Polyester film or PET-film is an extremely durable and tear resistant plastic with excellent electrical insulation properties. The PET-film is electrically isolation graded B (130°) and moisture repellent which makes it well suited for insulation of electrical products. The film is used as isolation in transformers, generators, PCBs, cabinets, enclosures, batteries, battery related products and electrical engines. The material is resistant against high temperatures, up to 150° working temperature in air and UL94 VTM-2 graded and UL746 (105°). The material is flexible and bendable and at the same time dimensionally stable, which makes the PET-film very suitable in mechanically demanding applications as well as foldable insulation boxes. The polyester film may be die-cut with folding points to achieve a box that encloses sensitive products. We convert other electrically insulating materials that are worth noting. Those materials are Nomex® and Formex® and can, like polyester film, be punched into foldable insulation parts.
