Tesa Tesaflex 53988 PVC Electrical Insulation Tape Black 20m 19mm 260% Elongation

Product Overview

Tesa Tesaflex 53988 is a black PVC electrical insulation tape used for bundling, insulating, marking, reinforcing, sealing, and protecting electrical cables and wires. Frequently utilized by electricians and installers in residential, commercial, and industrial contexts, it is constructed with a soft PVC backing and designed for flexible application around irregular surfaces. The tape offers electrical strength up to 5000 volts, making it suitable for a wide range of standard low and medium voltage applications.

What distinguishes this specific SKU is its high elongation at break of 260%, which allows for reliable application on curved and uneven surfaces without tearing. This reduces installation failures and helps maintain insulation integrity even in demanding or vibration-prone installations. It is particularly recommended for bulk procurement by electrical contractors, maintenance teams, and cable harness assembly operations requiring consistent stretch and conformity.
