Why choose it

This tape is built for professional use. The PVC backing is flexible and conforms well to irregular shapes, while the rubber adhesive provides strong initial tack and long-term holding power. Its self-extinguishing property adds safety in electrical applications, and the 8 kV dielectric strength ensures reliable insulation for low-voltage work up to 600 V. The black colour is standard for phase marking and general insulation, and the tape resists UV exposure, moisture, and common chemicals, making it suitable for both indoor and outdoor use.

Ideal use cases

• Insulating electrical splices and wire connections
• Repairing damaged cable jackets
• Bundling and harnessing wires in control panels
• Colour coding and marking of cables
• General maintenance and repair in industrial, commercial, and residential settings

Good to know

The tape is supplied on a standard 19 mm core and is easy to unwind by hand. It can be torn cleanly without tools, speeding up installation. Store in a cool, dry place to maintain adhesive performance. For best results, apply to clean, dry surfaces with sufficient tension and overlap at least half the tape width.
