Electrical/Electronic Insulation Tapes

Electrical insulation tapes are ideal for cable insulation and marking, and to meet international safety standards such as the IEC and IMQ. These tapes come in various colors and can be resistant to aging, weather, abrasion, and fire. Many businesses rely on high dielectric strength tape to provide consistent electrical insulation performance in demanding environments, especially where voltage protection and long-term reliability are required.

Electro Insulation Corporation now slits these tapes in-house on a CMC Cevenini E305 automatic log slitter. You can order high temperature electrical tape cut to the exact width your application needs, starting at 2 mm, with an indexing tolerance of ±0.1 mm.

Whether used in manufacturing, assembly, or maintenance, these tapes offer dependable protection against heat, abrasion, and environmental stress while supporting safe and efficient electrical system performance.

Characteristics of High-Temperature Electrical Tape

Excellent flexibility and adhesion
Conforms easily to irregular shapes and surfaces
High dielectric electrical insulation strength
High tensile electrical insulation strength
Superior tear, puncture, and solvent resistance
Superior solvent resistance
High voltage insulating wrap
Excellent edge tear resistance

These characteristics make high-temperature tapes suitable for complex assemblies where components must withstand electrical stress and thermal cycling. Many formulations maintain stable performance even in harsh industrial settings, offering a balance of mechanical strength and electrical protection. High dielectric strength tape further enhances insulation capabilities for applications that demand elevated voltage resistance.

Common Applications of High-Temperature Electrical Tape

Industrial repairs
Wiring harnesses
Insulates lead connection
Bundling/banding heavy conductor coils

In these applications, tape must deliver both mechanical durability and reliable electrical insulation. High-performance materials help prevent component failure by resisting heat, abrasion, and environmental exposure. As industries advance toward compact, high-output systems, the need for dependable insulating materials continues to grow.

Precision Tape Slitting on the CMC Cevenini E305

Consistent tape width matters on harness lines, in coil wrapping, and on automated taping equipment, where a roll that runs wide or narrow can stop a line or leave a gap in insulation. Electro Insulation slits tape on a CMC Cevenini E305, an automatic log slitter built for technical, dielectric, vinyl, PVC, and double-sided adhesive tapes.

What the E305 Means for Your Order

Narrow widths: Cuts start at 2 mm (0.08") and adjust in decimal increments, so specialty widths don’t need to be rounded to the nearest standard size.
Tight tolerances: An indexing tolerance of ±0.1 mm (0.003") keeps each roll in a run the same width.
Large master rolls: The E305 handles logs up to 1700 mm (67") wide and 305 mm (12") in diameter.
Your core size: Interchangeable mandrels fit cores from 1" to 3".
Clean, consistent cuts: A single driven rotating blade with an automatic pivoting angle makes each cut, and the cutting cycle runs automatically once a log is loaded.
Repeatable setups: Widths are programmed through a Siemens PLC with a touchscreen operator interface.
