Fita isoladora Tesa tesaflex 53988 fita elétrica PVC 25 m x 19 mm, preta

tesaflex 53988 is a PVC insulating tape designed for electrical applications, supplied in a 25 m roll with 19 mm width in black. The tape meets IEC 60454-3-1 requirements and is produced to be compliant with RoHS and REACH directives. It combines a 150 µm PVC carrier with a rubber-based adhesive to provide electrical insulation, protection against moisture and abrasion, and temperature stability for a range of wiring and maintenance tasks.

Advantages

The PVC construction and rubber adhesive deliver reliable dielectric performance and mechanical durability. A dielectric breakdown voltage of 7,000 V offers effective electrical insulation for typical installation and repair jobs, while resistance to ageing and moisture helps maintain integrity in indoor environments. The tape’s temperature resistance up to +90°C and moderate carrier thickness provide a balance of flexibility and tear resistance for wrapping, bundling and marking applications.

Suitable for

• Insulating and repairing electrical and electronic cables and connections
• Colour-marking wiring and identifying phases in installations
• Securing and bundling wires in household and light commercial equipment
• Protecting cable joints from abrasion and light moisture exposure

How to use

Ensure surfaces are clean, dry and free of oils or dust before application. Measure and cut the required length, then apply the tape with slight overlap while maintaining steady tension to create a uniform wrap. For insulating joints or connections, wrap from one side of the joint to the other, overlapping successive turns to ensure continuous coverage. Avoid stretching the tape excessively to prevent thinning of the carrier and adhesive.

Recommendations

Use this insulating tape for indoor electrical installations, routine repairs and colour-coding tasks. For outdoor or high-voltage permanent installations, select a tape or system rated specifically for those conditions. Store rolls in a dry place away from direct sunlight to preserve adhesive performance and material properties.
