What is Mylar Polyester Film?
Mylar polyester film is unparalleled in overall physical properties. Mylar is an exceptionally strong, flexible, durable film with properties that make it extremely suitable for most industrial applications. Inert to water, Mylar polyester acts as a moisture barrier and is unaffected by oil, grease, and aromatics. It remains tough, clear, and flexible from minus 100 degrees F to over 300 degrees F and will not yellow or become brittle under normal conditions. Polyester has excellent dielectric properties and can be used as an effective insulator in electrical applications. Available in the following formulations.
