Insulating Tape 3M Temflex 155 PCW 19 mm x 20 m, yellow

3M Temflex 155 PCW insulating tape, 19 mm x 20 m in yellow, is a PVC electrical insulation tape designed for general-purpose wire and cable insulation, color-coding and protective wrapping. The tape combines flexible backing with a pressure-sensitive adhesive to provide reliable dielectric insulation and temporary mechanical protection for electrical conductors during maintenance, repair and installation work. Its compact roll size makes it suitable for carrying in tool kits or keeping on a workbench for quick access.

Advantages

The tape offers good conformability around irregular shapes and maintains adhesion on common cable jackets and metal connections. Its PVC construction provides basic resistance to abrasion and moisture under normal indoor and sheltered outdoor conditions. The pressure-sensitive adhesive enables fast application without heating or special tools. The yellow color allows clear color-coding of circuits, phases or test points.

Suitable for

• Electrical insulation of wires and cable splices in domestic and light commercial installations
• Color-coding of conductors, phases and test leads
• Protective wrapping of connectors and temporary fixes during maintenance
• DIY and hobby electronics projects requiring flexible tape for insulation

Key specifications

• Material: PVC backing with pressure-sensitive adhesive
• Width: 19 mm
• Length: 20 m per roll
• Color: yellow
• Dielectric function: electrical insulation for low-voltage applications
• Application temperature: suitable for typical room-temperature work (consult manufacturer for extremes)

How to use

Clean and dry application surfaces before wrapping. Start the tape on the conductor or splice and stretch slightly while overlapping each wrap by about half the tape width to form a uniform insulating layer. For color-coding, apply a single layer to identify conductors; for insulation, apply multiple overlapping layers until the required thickness and coverage are achieved. Cut the tape with scissors or tear by hand if applicable, and press the end firmly to ensure adhesion.

Usage recommendations

Use this tape for low-voltage insulation, temporary repairs and color identification. It is not intended for permanent insulation of high-voltage conductors or for continuous exposure to elevated temperatures, chemicals or outdoor weathering; follow relevant electrical safety standards and consult manufacturer specifications when in doubt.
