3M™ Polyester Film Electrical Tape 1351W-1 is an electrical tape featuring a 1.0-mil white polyester film backing and an aggressive acrylic adhesive. Combining high dielectric strength (5,000V), smooth unwind, and superior flagging resistance, it is ideal for outer wrapping on visible white electronic coils.
Key Performance Highlights
- Pure white polyester backing provides clean aesthetic finish and high contrast for printing
- High-tack acrylic adhesive delivers instant hold without flagging
- UL Recognized Class 130°C component with 5,000V dielectric breakdown
- Resists solvent attack from varnish impregnation and circuit board washing fluids
Recommended Industrial Applications
Outer wrap on white coil assemblies, color-coded insulation, transformer coil margins
