Mylar is a heat-resistant polyester film that combines dielectric strength with moisture resistance. Mylar insulation is also flexible and won’t become brittle during normal use. This electrical insulator is useful over a wide range of temperatures, and resists many chemicals (except alcohol).

Interstate Specialty Products die cuts Mylar insulation for medtech, electronics, and industrial applications. For over 60 years, our Made in the USA manufacturing company has been die cutting electrical insulation materials like Mylar at our custom fabrication facility in Sutton, Massachusetts.

Interstate Specialty Products supplies die cut Mylar parts in various types, finishes, and thicknesses. For example, depending on your application’s requirements, we may recommend reflective Mylar sheets for die cutting, or clear Mylar rolls for slitting and laminating.

Applications for Mylar Insulation

Die cut Mylar is commonly used to make

  • bus bar, battery, and motor insulation
  • isolated wires and electronic components
  • flexible electronics

Ask Interstate Specialty Products if a polyethylene terephthalate (PTE) film like Mylar is the right choice for your application. There are multiple factors to consider.

For example, although Mylar is a useful electrical insulator over a relative temperature range, polyethylene naphthalate (PEN) films may be required for high temperatures. By understanding all of your thermal and electrical requirements, we can recommend the best electrical insulation material for custom fabrication.

Interstate Specialty Products die cuts Mylar insulation to size, and can apply a pressure sensitive adhesive (PSA) backing for easy installation. To learn how our insulation manufacturing capabilities can support your application, contact us on-line or call (800) 984-1811.
