Tesa 4600 Black Self-Amalgamating Tape 25 mm x 3 m

This self-amalgamating tape offers a stretchable, rubber-based solution for electrical insulation and sealing in industrial settings. Designed for use where durable, heat-resistant wraps are required, it provides an adhesive-free bond when stretched and wrapped, supplying a Compact insulating layer suited to maintenance and repair tasks across automation, electronics and mechanical environments.

• Withstands temperatures up to 260°C for high-heat applications
• Insulates at breakdown voltages of 8000V to protect circuits
• Stretchable speciality backing enables conformal wrapping and Seals
• Tensile strength of 33 N/cm resists mechanical stress during service
• Available in a 25mm width for targeted repairs and terminations

• Suitable for insulating cable joints and splices in control panels
• Ideal for sealing threaded fittings in high-temperature equipment
• Used for emergency repairs on wiring harnesses in automation lines
• Can be used for bundling and abrasion protection of sensor cables
• Used with Terminal blocks where Compact insulation is required

Each roll is supplied in a 3M length, enabling multiple small repairs from one unit.

It operates reliably between −60°C to 260°C, covering sub-zero storage and elevated process temperatures.

Yes, the material fuses to itself on stretch and wrap, forming a cohesive insulating layer without added adhesive.

The film has a thickness of 0.5mm, permitting use in confined assemblies while still providing insulation.
