Mylar® and Melinex® Polyester Film

Mylar® and Melinex® polyester films are flexible, exceptionally strong and durable translucent and clear films. They have a high tensile, tear and impact strength and remain tough and flexible at temperatures from -70°C to 150°C. Specific engineering functions include:

  • An electrical barrier in motors, transformers and wire, cables and many other uses in electronic and aerospace equipment.
  • A physical barrier in protective laminates for decals and book covers.
  • A thermal and electrical barrier in wire and cables.
  • A substrate for coating or laminating of food and medical packaging, as well as general printing and packaging applications.
  • A mechanical interface in membrane switches.
  • Mylar® and Melinex® are registered Trade Names of Celanese.

Mylar A® is a flexible, exceptionally strong and durable transparent Polyester film with a maximum working temperature of 200°C. It has high tensile, tear and impact strength, high dielectric strength, temperature durability, and is dimensional stable. Lohmann are able to supply Mylar A® in many formats including: sheets, rolls and die-cuts, either with or without a pressure sensitive adhesive.

Mylar A® has many applications including :
