Electrical tape 3M 7100240608 PVC 20m 19mm White

3M 7100240608 is a white PVC electrical tape designed for insulation and surface protection in electrical and general-purpose applications. The tape combines flexible PVC backing with a pressure-sensitive adhesive to offer consistent coverage and reliable dielectric isolation for wires, cables, and connections. With a length of 20 meters and a width of 19 mm, the tape is suited for routine repairs, bundling, color marking, and protective wrapping where a slim, conformable tape is required.

Advantages

The PVC construction provides good conformability and mechanical protection while maintaining electrical insulation properties at common operating voltages. Its pressure-sensitive adhesive enables quick application and firm adhesion to common electrical substrates such as copper, PVC insulation, and other plastics. The white color offers neutral visual contrast for identification or marking without interfering with surrounding components.

Suitable for

• Insulating splices and wire terminations
• Temporary fixes and cable bundling
• Color-coding and marking of wiring
• Surface protection of panels and housings
• General-purpose sealing and light mechanical protection

Key specifications

• Material: PVC backing with pressure-sensitive adhesive
• Color: White
• Length: 20 m
• Width: 19 mm
• Thickness: 0.18 mm
• Dielectric function: Electrical insulation for typical low-voltage applications
• Flexibility: Conformable to curved surfaces and irregular shapes

How to use

Ensure the surface and conductors are clean, dry, and free of oils or debris before application. Cut an appropriate length of tape, overlap successive wraps by approximately 50% to build up insulation thickness, and press the tape firmly to form a continuous, smooth layer. For splices, start the wrap onto the existing insulated conductor and extend beyond the splice area to secure a reliable seal. Avoid stretching the tape excessively during application, as this can reduce insulating thickness and long-term adhesion.

Usage recommendations

Use this PVC electrical tape for indoor and sheltered outdoor applications at ambient temperatures typical for building and equipment installations. Store the product in a cool, dry place away from direct sunlight to maintain adhesive performance. For high-temperature, outdoor UV-exposed, or specialized high-voltage needs, consider selecting an alternative tape formulated for those conditions.
