Electrical insulation materials have excellent dielectric strength along with other desirable properties such as resistance to heat, cold, moisture, chemicals, and radiation.

Interstate Specialty Products supplies die cut insulation for medtech, electronics, and industrial applications. For over 60 years, our Made in the USA manufacturing company has been die cutting electrical insulation and thermal management silicones at out custom fabrication facility in Sutton, Massachusetts.

Insulation Types

  • Fish paper is often a good choice if you need an electrical insulator for oil-filled transformers.
  • Mylar combines electrical insulation with moisture resistance.
  • Formex provides UL-94 flame resistance
  • Kapton electrical insulation also has a high flammability rating, and can resist many different chemicals.
  • Silicone insulation combines excellent electrical and thermal insulation for applications like electrical conductor seals, outdoor electrical enclosures, and high voltage insulation.

Tell us about your application, and we’ll recommend an electrical insulation material that meets your requirements for cost and performance. Our die cutting services meet demanding specifications in a range of part sizes, and to exacting tolerances for dimensionally-stable materials.

We can also laminate die cut insulation with other materials and adhesives, and manufacture insulating materials via precision die cutting or roll slitting methods. To learn how our insulation manufacturing capabilities can support your application, contact us on-line or call (800) 984-1811.
