3M™ Polyester Film Electrical Tape 5 is an economical, general-purpose electrical tape with a 1.0-mil polyester film backing and a thermosetting rubber adhesive. It provides high dielectric breakdown (5,000V), excellent tensile strength, and Class 130°C thermal rating for coil covers, capacitor insulation, and motor layer wrapping.
Key Performance Highlights
- Thin 2.5 mil profile provides 5,000V dielectric barrier without consuming coil winding space
- Thermosetting rubber adhesive cures during oven bake to resist solvent attack
- High tensile strength and tear resistance across industrial winding machines
- UL Recognized Class 130°C component for transformer manufacturing
Recommended Industrial Applications
Coil outer wrapping, capacitor layer insulation, core insulation in fractional HP motors
