Mylar®and Melinex® Polyester Film

Mylar® and Melinex® polyester films are flexible, exceptionally strong and durable translucent and clear films produced by DuPont. They have a high tensile, tear and impact strength. They 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 a host of 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 General graphics and packaging applications.
  • A mechanical interface in membrane switches.

This is a flexible, exceptionally strong and durable transparent Polyester film with operating temperature up to 150 deg c. It has high tensile, tear and impact strength, high Dielectric Strength, temperature durability, and dimensional stability Mylar A is very versatile and can be supplied in sheets, reels and die cut to customer drawings/specifications.

Mylar A has many applications including :

  • PSU’s
  • Membrane Switches
  • Cable Insulation
  • Motors 
  • Heating Elements
