3M™ Polyester Film Electrical Tape 1350F-2Y is a heavy-duty electrical tape featuring a 2.0-mil yellow polyester backing with a flame-retardant acrylic adhesive. Engineered for applications demanding higher puncture resistance and superior dielectric performance (7,000V), it meets UL 510 flame retardancy requirements for power transformers.
Key Performance Highlights
- 2.0 mil thick polyester backing provides increased dielectric strength (7,000V) and puncture resistance
- UL 510 Recognized flame retardant (File E17385) for switch-mode power supplies
- Acrylic adhesive system ensures excellent flagging and solvent resistance without heat cure
- Extra mechanical barrier protection against sharp magnet wire leads
Recommended Industrial Applications
Heavy-duty transformer coil wrapping, high-voltage layer insulation, applications requiring puncture resistance
