3M Electrical Tape 12mm x 33m Polyimide Film Amber Heat Resistant Insulation T120512

3M T120512 Amber Polyimide Film Electrical Tape features a 12mm width and 33 meters length, specifically engineered for demanding electrical insulation tasks in industrial, mechanical, and electronic manufacturing environments. The acrylic adhesive combined with polyimide film backing offers excellent electrical insulation properties with a breakdown voltage rating of 3000V, enabling reliable protection of sensitive components.

With a maximum operating temperature of 155°C, this tape is ideal for high-temperature insulation applications including solder masking for printed circuit boards and securing leads on terminal boards, wire harnesses, and capacitors. The tape's 0.076mm thin profile reduces bulk for precision in tight spaces while maintaining durability and flame resistance per UL 510 certification.

The acrylic pressure-sensitive adhesive ensures ease of application and clean removal without leaving residue, preserving substrate integrity. Its tensile strength of 53N/cm delivers mechanical robustness against wear, while the amber color assists with visual identification during electrical work.

This tape maintains reliable performance in extreme environments and can be customized by cutting to specific widths to suit specialized projects. For optimal shelf life, it should be stored in humidity-controlled environments to preserve adhesive and backing performance.
