Description

---

Polyester foil (Mylar) is a flexible and transparent electrical insulating material. PET foil combines many positive properties with a favorable price, which is why they are used in a wide range of industries. Also known as BoPET, it has good thermal insulation properties that correspond to class B (130° C). PET foil has a unique combination of mechanical strength, thermal and chemical resistance and low adhesion to many polymeric materials. Polyester film is very tear resistant and resilient.

Areas of application
