Tape TESA 4163 33m Black Acrylic PVC

Tape TESA 4163 is a PVC insulation and repair tape with an acrylic adhesive, designed for use around electronics and general indoor and outdoor applications. The tape is 33 m long and 12 mm wide, offering good elongation and temperature resistance. Its special acrylate adhesive gives high UV and heat resistance, and the material is resistant to acids and solvents, making it suitable for marking, insulating and temporary repairs.

Advantages

tesaflex® 4163 combines soft PVC backing with an acrylate adhesive to provide long-term outdoor durability (up to 104 weeks), high temperature resistance (up to 105 °C), and chemical resistance to acids and solvents. The tape offers strong tensile performance and good elongation at break, which supports reliable insulating and repair use around cables and electronic components.

Suitable for

• Electrical insulation and cable marking
• Temporary repairs on cables and housings
• Indoor and outdoor sealing where UV resistance is required
• Applications requiring resistance to acids and solvents

How to use

Clean and dry the surface before applying the tape. Cut or tear the required length, wrap it firmly around the cable, joint or surface with slight overlap, and press to ensure good contact between the adhesive and the substrate. For insulating or marking cables, align the tape so markings remain visible; for repairs, cover the damaged area fully and smooth edges to reduce peeling. Store unused rolls in a cool, dry place.

Recommendations

Use tesaflex® 4163 for electrical insulation, cable marking and short-term outdoor repairs. Avoid prolonged exposure to temperatures above the specified limit and verify compatibility with specific solvents if used in chemically aggressive environments.
