Professional-Grade Mylar Electrical Insulation Tape for Demanding Electrical & Industrial Applications
This 50m roll of multi-coloured Mylar electrical insulation adhesive tape, also known as polyester or Mara tape, is designed for demanding industrial and electrical applications. Manufactured from high-quality PET (polyester film), this tape provides outstanding tensile strength, electrical insulation, and thermal resistance.
The tape features a pressure-sensitive acrylic or silicone adhesive, ensuring excellent adhesion to a wide range of surfaces while maintaining stability under heat and chemical exposure. Its durable construction makes it suitable for long-term use in professional environments.
Widely used in the electrical and electronics industry, this Mylar tape is ideal for insulating, wrapping, fastening, bundling, and protecting electrical components such as transformers, motors, coils, and capacitors.
Available in multiple colours, it is also perfect for colour-coding, labelling, and organised cable management in workshops, factories, and maintenance operations.
Why Choose Our Mylar Polyester Tape?
Unmatched Durability: The Polyester (PET) film backing provides exceptional tensile strength and resistance to punctures, tearing, and abrasion.
Superior Insulation: Offers excellent dielectric strength, making it a safe and trusted choice for insulating electrical components up to high voltages.
Built for Tough Conditions: Resistant to a wide range of chemicals, solvents, and moisture. Performs reliably in temperatures from -40°C to 130°C+.
Clean & Secure Bond: The aggressive acrylic adhesive ensures a strong, long-lasting hold without oozing or leaving heavy residue.
Typical Applications:
Electrical Insulation: Insulating and colour-coding wires, coils, transformers, capacitors, and motor windings.
Banding & Fastening: Securing cable harnesses, bundles, and components.
Protective Wrapping: Shielding parts from abrasion, corrosion, and chemical splash.
General Industrial Use: Masking, splicing, repairable labelling, and general maintenance in workshops and factories.
