3M™ Heavy-Duty Polyester Tape 1350T-3 is a 4.0-mil electrical tape featuring a 3.0-mil triple-layer yellow polyester backing and an acrylic adhesive. Engineered for primary-to-secondary high-voltage isolation in switch-mode power supplies, it delivers 8,000V dielectric barrier and complete pinhole immunity.

Key Performance Highlights

  • 3.0 mil triple-layer laminated construction delivers immense 8,000V dielectric barrier
  • Pinhole-free multi-layer film prevents high-voltage breakdown and arc-over
  • Yellow visual identifier for primary-to-secondary high-voltage barrier insulation
  • High tensile strength and tear resistance under automated coil tension

Recommended Industrial Applications

Heavy-duty reinforced insulation in SMPS power transformers, industrial inverter coil wraps
