Mylar Polyester Type D 3 x 100 Roll
Mylar Polyester Type D 3 x 100 Roll is manufactured from high-quality polyester (PET) film engineered to provide exceptional mechanical, electrical, and thermal performance. Known for its outstanding dimensional stability and dielectric properties, Mylar Type D is widely trusted for demanding industrial and electrical insulation applications.
One of the primary advantages of Mylar Polyester Type D is its excellent dielectric strength, making it an ideal material for insulating motors, transformers, generators, capacitors, and electrical assemblies. It helps ensure reliable electrical performance while maintaining long-term insulation integrity under demanding operating conditions.
The material also offers excellent tensile strength and tear resistance, allowing it to withstand mechanical stress during fabrication and installation. Its low moisture absorption contributes to consistent dimensional stability even in humid environments, helping maintain precision and long-term reliability.
Mylar Polyester Type D exhibits good resistance to chemicals, oils, solvents, and environmental exposure. Its smooth surface and flexibility make it easy to cut, die-cut, laminate, and fabricate into custom insulation components, protective barriers, labels, and industrial assemblies.
Because of its excellent combination of electrical insulation, mechanical durability, thermal stability, and fabrication versatility, Mylar Polyester Type D 3 x 100 Roll is widely used in electrical manufacturing, electronics, aerospace, automotive, telecommunications, and general industrial applications requiring dependable high-performance polyester film.
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.
