3M™ Triple-Layer Polyester Tape 1350T-1 is engineered with a laminated triple-layer polyester film backing and an acrylic adhesive. The multi-layer structure virtually eliminates pinhole defects, providing high-integrity dielectric isolation for switch-mode power transformers requiring reinforced safety insulation.

Key Performance Highlights

  • Triple-layer laminated polyester film provides pinhole-free reinforced insulation barrier
  • High solvent and flagging resistance across automated bobbin winding operations
  • UL Recognized Class 130°C component for high-frequency switching converters
  • Transparent clear carrier permits optical inspection of underlying windings

Recommended Industrial Applications

Reinforced triple insulation for switch-mode power transformers, SMPS barrier tape
