Mylar tape is widely used in electronic and electrical, new energy and high-end manufacturing fields because of its excellent insulation performance, temperature resistance and mechanical strength.
⚡

Transformer and Motor Manufacturing

Mylar tape is the core insulating material of various power transformers, pulse transformers, audio transformers, motors and motor coils. It is mainly used for winding interlayer insulation, coil end wrapping, lead wire insulation fixation, etc., which can effectively prevent coil short circuit and improve insulation grade and operation stability of equipment.

🔌

Electronic Components and Wiring Harness

Used for insulation, isolation, fixation and identification in capacitors, inductors, resistors, coils and other components. In wire harness processing, it can be used for wire harness bundling, branch fixing and insulation protection, especially for electronic wire harness which needs high temperature resistance and aging resistance.

💻

PCB and Electronic Assembly

In the process of PCB manufacturing and electronic assembly, Mylar tape is often used for gold finger shielding, solder joint protection, insulation reinforcement, line isolation and so on. Its high temperature resistance makes it possible to be used in high temperature processes such as reflow soldering and wave soldering to protect sensitive areas from solder pollution.

🔋

Power Supply and Electrical Equipment

In switching power supply, power adapter, charger, inverter, UPS and other equipment, Mylar tape is used for internal line insulation, component fixation, enclosure and circuit board isolation to improve the safety and reliability of the equipment.

🟢

New Energy Battery (Lithium Battery / Energy Storage)

In the manufacture of lithium battery cells, Mylar adhesive tape is used for the insulation of tabs, the insulation between cells and protective plates, and the surface protection and fixation of cells. Some flame-retardant Mylar tapes can also be used for insulation protection of energy storage systems to improve the safety of battery packs.

🔧

Other Industrial Applications

It can also be used for thin film switches, FPC insulation, nameplate fixing, surface shielding of metal parts, and various industrial scenes requiring insulation, temperature resistance and solvent resistance.

❓ Frequently Asked Questions
Q What is Mylar tape and what is it made of?
Mylar tape is a polyester film (PET) tape coated with acrylic adhesive. The PET carrier provides excellent mechanical strength, dimensional stability and electrical insulation, while the acrylic adhesive offers reliable bonding performance across a wide temperature range.
Q What voltage resistance does Mylar tape offer?
Depending on the product model, Mylar tape offers voltage resistance ranging from 3.0 KV up to 6.2 KV. For example, the HY100 series (0.06 mm thickness) provides 4.2 KV, while the HY100-B series (0.08 mm thickness) provides 6.2 KV, making them suitable for a wide range of electrical insulation applications.
Q What colors are available for Mylar tape?
Mylar tape is available in a wide variety of colors including Yellowish, Deep Yellow, Blue, Red, Green, Black, White, and Transparent. This allows easy color-coding for identification, circuit isolation, or component marking in manufacturing processes.
Q Can Mylar tape withstand high-temperature processes like reflow soldering?
Yes. Thanks to its PET carrier and acrylic adhesive system, Mylar tape is well-suited for high-temperature processes such as reflow soldering and wave soldering. It effectively protects sensitive areas like gold fingers and solder joints from heat damage and solder contamination during PCB assembly.
Q Is Mylar tape suitable for lithium battery manufacturing?
Absolutely. Mylar tape is widely used in lithium battery cell manufacturing for tab insulation, cell-to-protective-plate insulation, and surface protection of battery cells. Flame-retardant variants are also available for use in energy storage systems to enhance overall battery pack safety.
Q How does Mylar tape compare to 3M polyester film tape?
Several HY100 series products are direct equivalents of 3M polyester film tapes. For instance, HY100-1 is equivalent to 3M 1350F-1Y, HY100-7 to 3M 1350F-1W, and HY100-8 to 3M 1350F-1BL. These products offer comparable insulation performance and adhesion properties, providing a cost-effective alternative for industrial applications.
