Electrical tape 3M 7100184820 Black PVC 25m x 25mm x 0.15mm

3M 7100184820 Black PVC electrical tape is a pressure-sensitive insulating tape designed for electrical insulation, fastening, and surface protection. With a length of 25 m, width of 25 mm and a film thickness of 0.15 mm, this tape combines conformability and tensile strength to wrap wires, insulate connections and protect surfaces from abrasion and moisture. The black PVC backing provides good resistance to abrasion and moderate chemical exposure while the adhesive offers reliable adhesion to common wiring insulation materials.

Advantages

The PVC construction delivers flexibility and conformability for wrapping irregular shapes and joints. Its 0.15 mm thickness balances mechanical protection with compact layering for insulation. The adhesive system provides stable tack and holding power on PVC, rubber and enamelled wire insulation. The black color ensures visual uniformity and reduces light reflection on installations where appearance or concealment is needed.

Suitable for

• Insulation of electrical splices and terminal connections
• Bundling and securing cables and harnesses
• Minor surface protection against abrasion and moisture
• Colour-coding or marking in black where contrast is required

Key specifications

• Material: PVC (polyvinyl chloride) backing
• Length: 25 metres
• Width: 25 millimetres
• Thickness: 0.15 millimetres (film thickness)
• Colour: Black
• Adhesive type: pressure-sensitive adhesive formulated for electrical insulation
• Properties: conformable, abrasion-resistant, moisture resistant

How to use

Ensure surfaces are clean, dry and free of oil, dust or corrosion before application. Start by partially unrolling the tape, anchoring the end, and stretching slightly while wrapping to achieve conformity over irregular shapes. Overlap each turn by approximately 50% to build insulation thickness, and finish by pressing the tape firmly to create a good bond. For splices and high-voltage applications, follow relevant electrical codes and build the required number of layers to meet insulation ratings.

Usage recommendations

Store the tape in a cool, dry place away from direct sunlight and heat sources to preserve adhesive performance. For long-term outdoor exposure or applications requiring higher temperature or chemical resistance, select a tape specified for those conditions. Dispose of used tape according to local regulations for adhesive-coated materials.
