Overview
Mylar Tape, also known as polyester film tape, is a high-performance insulation material widely used in the electronics and electrical industries. This tape is manufactured with a PET (polyethylene terephthalate) film as the carrier, coated with flame-retardant acrylic or rubber-based adhesive, ensuring strong adhesion and reliable thermal and electrical performance.
Whether you’re looking to insulate transformers, wrap motor coils, or protect circuit boards during manufacturing processes, Mylar Tape offers excellent resistance to temperature, chemicals, and flame—making it an indispensable component for critical applications.

Product Features
1. Flame Retardant Performance
Mylar Tape complies with UL 510 standards for flame-retardant insulation materials. It holds a 94 V-0 flame retardant grade, providing enhanced safety in high-risk environments such as motors, power transformers, and industrial control systems.
2. High Dielectric Strength
With a breakdown voltage of up to 7.5 kV, Mylar Tape ensures excellent electrical insulation, preventing current leakage and ensuring operational stability of electronic and electrical systems.
3. Thermal Stability
Rated for continuous use at temperatures up to 130°C, this tape is suitable for Class B insulation applications. It performs reliably across a wide range of thermal environments, from -10°C to +130°C.
4. Strong Adhesion & Mechanical Strength
The acrylic adhesive ensures a peel adhesion strength of up to 300 N/25mm and a tensile strength of 3 kN/m, providing secure and lasting fixation of components. Elongation values of over 100% ensure flexibility without breakage.
5. Chemical and Solvent Resistance
Engineered to resist chemical corrosion, Mylar Tape performs well even in harsh environments where exposure to oils, solvents, and cleaning agents is common.
Applications
Mylar Tape is commonly used for:
- Transformer Coil Wrapping: Provides insulation for internal windings and outer wrapping of coils.
- Motor Insulation: Ideal for stator coil covering and fixing motor windings.
- Capacitors & Relays: Used as an insulation layer between components to prevent arcing and short circuits.
- PCB Manufacturing: During electroplating or soldering processes, Mylar Tape is used to cover gold fingers or sensitive parts to protect against solution immersion and contamination.
- Voltage Regulators & Power Electronics: Ensures high thermal endurance and insulation in compact and heat-intensive devices.
- General Insulation & Fixing: Applicable to a wide variety of electrical components requiring durable bonding and insulation.
