Tesa 4657 4657 Duct Tape, 50 m x 25mm, Black, Acrylic Coated Finish

This duct tape is a cloth-based adhesive tape designed for demanding industrial environments where heat resistance and strong tensile performance are required. It combines an acrylic-coated cloth backing with a natural rubber adhesive to provide robust surface adhesion and mechanical strength while operating at elevated temperatures. The product is intended for applications that require a balance of durability and controlled stretch.

• 180°C maximum operating temperature provides high-heat performance
• 105N/cm tensile strength delivers strong load-bearing capacity
• 4.6N/cm adhesion strength ensures secure initial tack
• 0.29mm thickness gives compact, manageable profile
• 7.5% elongation at break limits unwanted stretch

• Suitable for sealing ducts exposed to elevated temperatures
• Ideal for fixing and bundling cables in heat-prone areas
• Used for temporary repairs on insulated surfaces
• Can be used for masking during high-temperature processes

The tape uses an acrylic-coated cloth backing that combines flexibility with structural strength.

The natural rubber adhesive provides firm initial adhesion suitable for many common industrial surfaces.

It meets DIN EN and LV 312-1 standards relevant to its class and operating conditions.

With 7.5% elongation at break, it offers controlled stretch to maintain position without excessive sagging.
