3M™ 1205

3M™ Polyimide Film Electrical Tape 1205 is a high-performance electrical insulation tape featuring a polyimide film backing and a pressure-sensitive acrylic adhesive. Engineered for extreme environments, it offers reliable thermal resistance from -40°C to +155°C, making it ideal for advanced electronic applications.

This flame-retardant, solvent-resistant tape excels in environments requiring thin yet durable insulation – such as transformer wrapping, PCB solder masking, and harness bundling. Fully UL listed and RoHS 2011/65/EU compliant, it meets the safety and quality demands of the modern electronics industry.

Applications

  • Wave solder masking in printed circuit board (PCB) assembly

  • Insulating transformers, capacitors, and wire harnesses

  • Anchoring terminal leads and boards

  • Protection from heat and solvents in precision electronics

  • High-temp applications across electronic manufacturing
