PVC Insulation Tape 3M 764S50 — black, 50 mm x 33 m

3M 764S50 is a black PVC insulation tape measuring 50 mm x 33 m engineered for electrical insulation, bundling and color-coding tasks. The tape provides flexible, conformable coverage that adheres reliably to wires and cable harnesses, offering basic protection against abrasion and moisture in indoor environments and light-duty outdoor applications where mechanical stresses are limited.

Advantages

The PVC construction delivers good flexibility and conformability for wrapping irregular shapes and joints, while the pressure-sensitive adhesive ensures consistent initial tack and retention on common insulating materials. Its 50 mm width covers larger cable bundles rapidly, reducing installation time compared with narrow tapes. The black color is suited for concealment, phase identification or standardized marking in maintenance and installation workflows.

Suitable for

• Electrical wire insulation and minor repair of insulation on power and control cables
• Bundling and securing cable runs in panels, conduits and behind equipment
• Color-coding, marking or phase identification in maintenance and installations
• General-purpose sealing against dust and light moisture in indoor or sheltered areas

Key specifications

• Material: PVC backing with pressure-sensitive adhesive
• Color: Black
• Width: 50 mm
• Length: 33 m
• Typical electrical insulation use: low- to medium-voltage applications for mechanical and moisture protection (basic)
• Flexibility: conforms to irregular shapes and cable junctions
• Suitable environment: indoor and light-duty outdoor (sheltered) use

How to use

Begin with clean, dry surfaces — remove dust, oil and loose particles for optimal adhesion. Unwind the tape and apply with moderate tension, overlapping each wrap by about half the tape width to ensure continuous coverage. For terminating or insulating joints, extend the wrap several millimetres beyond the damaged area and smooth the tape to eliminate air pockets. Cut the tape with a sharp blade or by tearing where appropriate, and press firmly along the length to secure the adhesive bond.

Usage recommendations

Use this PVC insulation tape for indoor electrical work, routine maintenance and temporary repairs. Avoid prolonged exposure to direct sunlight, extreme heat or prolonged immersion in water. For high-voltage, permanent outdoor or critical safety applications, refer to applicable electrical standards and select insulating materials rated specifically for those conditions.
