3M™ Epoxy Film Electrical Tape Super 10 is a 5-mil Class 155°C (Class F) insulating tape constructed with a flame-retardant epoxy film backing and thermosetting rubber adhesive. Delivering exceptional dielectric strength (6,500V) and solder flux resistance, it is widely specified for wrapping relays, solenoid coils, and transformers requiring high mechanical toughness.
Key Performance Highlights
- Tough epoxy film backing delivers outstanding puncture and cut-through resistance
- UL Recognized Class 155°C (Class F) and UL 510 flame retardant
- Thermosetting adhesive bonds strongly and resists degradation from varnishes and chemicals
- Resists solder iron contact and wave soldering thermal shock
Recommended Industrial Applications
Wrapping relays, solenoid coils, transformer outer wraps, solder-resistant barrier in wave soldering
