Insulation Tape 3M SUPER88-38X33 — 3M SUPER88, PVC electrical tape, 38 mm x 33 m, black

3M SUPER88-38X33 is a black PVC electrical insulation tape with 38 mm width and 33 m length, designed for electrical insulation, bundling, color coding and general-purpose repairs. The tape delivers dielectric protection while remaining flexible enough to conform to irregular surfaces and tight corners. It is intended for use by professional electricians and for DIY tasks where a durable, flexible vinyl tape is required.

Advantages

The PVC construction offers flame-retardant properties and consistent insulating performance across typical temperature ranges encountered in building and maintenance work. Its adhesive system provides good initial tack and long-term adhesion to common substrates such as copper, PVC conduit and insulated cables. The tape resists abrasion and maintains flexibility over time, allowing reliable wrapping, sealing and color-coding of wiring harnesses and cable assemblies.

Suitable for

• Electrical insulation of splices and terminations
• Bundling and securing cable assemblies
• Color-coding wires and phases
• Temporary repairs and protective wrapping
• General-purpose indoor maintenance and DIY electrical work

Key specifications

• Material: PVC (vinyl) backing
• Adhesive type: pressure-sensitive rubber-based adhesive
• Width: 38 mm
• Length: 33 m
• Color: black
• Dielectric performance suitable for typical low-voltage insulation applications
• Flame-retardant properties in line with vinyl electrical tape standards
• Flexible and conformable to irregular surfaces

How to use

Clean and dry the surfaces to be taped to ensure optimal adhesion. Start the wrap with a small overlap and stretch the tape slightly while applying to achieve a snug, conforming layer. Overlap each turn by approximately half the tape width for continuous coverage and to build the required insulation thickness. For splices or terminations, add multiple layers until the mechanical and electrical protection requirements are met. Cut the tape cleanly with scissors or tear by hand if appropriate, and press the final end to ensure it adheres securely.

Usage recommendations

Store the tape in a cool, dry place away from direct sunlight to preserve adhesive performance. Avoid exposure to high temperatures or solvents that can degrade the vinyl or adhesive. For permanent or high-voltage installations, follow applicable electrical codes and consider products specifically rated for the required voltage and environmental conditions.
