Comparison: 3M™ Temflex™ 165 versus other vinyl electrical tapes on the market

The market for vinyl electrical tapes offers numerous references. Here is how the 3M™ Temflex™ 165 compares to common alternatives.

Comparison table of the main vinyl electrical tapes

Product	Manufacturer	Nominal voltage	Max. temp.	Thickness	Main use
Temflex™ 165	3M	600 V	80 °C	0.18 mm	General insulation, low-voltage wiring
Super 33+™	3M	600 V	105 °C	0.18 mm	Demanding applications, outdoor, moisture
Super 88™	3M	600 V	105 °C	0.21 mm	Harsh environments, high mechanical strength
Scotch® 35	3M	600 V	90 °C	0.18 mm	Color coding, light insulation
Tesa 4600	Tesa	400 V	70 °C	0.15 mm	Domestic insulation, general use
Advance AT7	Advance Tapes	600 V	80 °C	0.18 mm	General insulation, industrial wiring

The Temflex™ 165 compares well against entry- and mid-range tapes. It offers a nominal voltage of 600 V where some competitors stop at 400 V.

Compared to 3M's premium references like the Super 33+™ or the Super 88™, it falls behind on temperature resistance and resistance to humid environments. These references are preferred for outdoor installations or those subject to severe constraints.

The Temflex™ 165 remains the logical choice for routine indoor electrical insulation: low-voltage wiring, junctions, and repairs. A solid performance/practicality ratio for daily use in workshops or on construction sites.

Application tips and best practices for Temflex™ 165 tape

Proper application makes all the difference. The Temflex™ 165 tape provides its best performance when a few simple rules are followed.

Prepare the surface before any application. The cable or conductor must be clean, dry, and free of grease. A dirty surface compromises adhesion and reduces the effectiveness of the electrical insulation.

Apply the tape with an overlap of at least 50% of the width at each turn. This overlap ensures insulation continuity with no weak points along the entire length of the connection.

Stretch the tape slightly during winding. The vinyl deforms under tension and perfectly contours irregular shapes, such as junctions or splices.

Always finish the wrapping with one or two turns without stretching. This prevents the end from peeling off due to the elastic shrinkage of the film.

Observe the minimum application temperature recommended by 3M, generally around +0 °C. Below this, the adhesive loses its effectiveness and the vinyl becomes less flexible.

A few points to remember:

• Cut the tape with scissors or a utility knife, not by tearing it by hand
• Do not expose the applied tape to temperatures above 105 °C continuously
• Store the roll away from direct light and moisture to maintain its properties
• Use multiple layers for voltages above 600 V
