Nastro TESA 4163 nero 33m acrilico PVC

tesaflex® 4163 is a premium black PVC adhesive tape designed for electronic applications and general insulation tasks. Made from soft PVC with an acrylate-based adhesive, the tape combines flexibility with resistance to UV, temperature and certain chemicals, making it suitable for both indoor and outdoor use.

Advantages

The acrylate adhesive ensures high UV and temperature resistance and provides reliable adhesion on cables and other surfaces. With good elongation and tensile strength, the tape can be used for marking, insulating and light repairs. It is resistant to acids and solvents and remains functional outdoors for extended periods.

Suitable for

• Insulating electrical cables and components
• Marking and color-coding wires
• Temporary repairs and bundling of cables
• Indoor and outdoor applications requiring UV and temperature resistance

Key specifications

• Material: soft PVC backing
• Adhesive: acrylate-based
• Color: black
• Length: 33 m
• Width: 38 mm
• Elongation at break: 250%
• Tensile strength: 30 N/mm²
• Temperature resistance: up to 105 °C
• Outdoor durability: up to 104 weeks

How to use

Ensure surfaces are clean, dry and free of oil or dust before application. Cut or tear the tape to the required length and wrap it smoothly around cables or surfaces, applying firm pressure to activate the adhesive. Overlap each turn slightly for continuous coverage when insulating. For outdoor use, ensure full adhesion by pressing along the edges to reduce water ingress.

Recommendations

For electrical insulation and marking, use tesaflex® 4163 at ambient temperatures and avoid applying to surfaces below recommended temperature ranges. Store rolls in a cool, dry place away from direct sunlight to maintain adhesive performance.
