Mylar Polyester Type A 4 x 100 Roll
Mylar Polyester Type A 4 x 100 Roll is manufactured from high-quality PET polyester film designed to provide exceptional electrical, mechanical, and thermal performance. Known for its outstanding dielectric strength and excellent dimensional stability, Mylar Type A is a preferred insulation material for demanding industrial and electrical applications.
One of the key advantages of Mylar Polyester Type A is its excellent electrical insulating properties. The material is commonly used for insulating motors, transformers, generators, capacitors, switchgear, and electrical assemblies where reliable dielectric performance is critical. Its consistent insulation characteristics help improve equipment reliability and operational safety.
The film also offers high tensile strength, tear resistance, and excellent dimensional stability, allowing it to maintain its shape and performance under mechanical stress and varying environmental conditions. Its low moisture absorption helps preserve both electrical and mechanical properties in humid environments.
Mylar Polyester Type A provides good resistance to oils, greases, chemicals, and many industrial solvents, making it suitable for demanding manufacturing environments. It is easy to cut, slit, laminate, die-cut, and fabricate into custom insulation components, protective barriers, labels, and precision-engineered parts.
Thanks to its excellent combination of electrical insulation, durability, flexibility, and fabrication versatility, Mylar Polyester Type A 4 x 100 Roll is widely used across electrical manufacturing, electronics, aerospace, automotive, telecommunications, renewable energy, and industrial engineering applications.
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.
