Insulating Tape Coroplast 302-25-RD, red, 25 m × 15 mm

Coroplast 302-25-RD is a red insulating tape designed for electrical insulation and general-purpose bundling. The tape is 25 meters long and 15 millimeters wide, offering a compact roll size suitable for routine wiring tasks and maintenance. It provides basic mechanical protection and color-coding for cables, harnesses, and small electronic assemblies used in domestic, workshop, and light industrial environments.

Advantages

This insulating tape combines flexibility and adhesion to conform to irregular surfaces and maintain contact with wires and components. Its red color enables quick visual identification and systematic color-coding in multi-conductor installations. The tape roll format and moderate width make it easy to handle and apply without specialised tools. Designed for electrical use, the tape resists everyday wear associated with handling and light mechanical stress in wiring applications.

Suitable for

• Cable insulation and splicing for low-voltage circuits
• Color-coding of wiring harnesses and cable bundles
• Temporary repairs and securing loose wires
• Light mechanical protection for electronic components and connectors

Key specifications

• Color: red
• Length: 25 m
• Width: 15 mm
• Material: flexible insulating film (pressure-sensitive adhesive backing)
• Intended use: electrical insulation and bundling

How to use

Clean and dry the surfaces to be taped to ensure the adhesive bonds properly. Start the wrap with an initial overlap and apply the tape with steady tension, covering the joint or exposed conductor fully and overlapping successive turns by about half the tape width for uniform coverage. For bundles and color-coding, wrap a single layer or multiple layers as needed to achieve the desired visibility and mechanical hold. Trim the tape with scissors or a knife and press the end of the tape firmly to secure the adhesive bond.

Usage recommendations

Use this red insulating tape on low-voltage electrical systems and for non-critical mechanical protection. Avoid exposing the tape to prolonged high temperatures, solvent exposure, or continuous outdoor weathering if long-term performance is required. For permanent high-voltage insulation or where specific fire or environmental ratings are necessary, select a tape specified for those conditions.
