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, Mara 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 system to improve the safety of battery packs.

Other Industrial Applications

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

Frequently Asked Questions
Q1 What is Mylar tape and what is it made of?
Mylar tape is a polyester (PET) film-based adhesive tape coated with acrylic adhesive. It combines the mechanical strength and dimensional stability of PET film with the excellent bonding properties of acrylic glue, making it ideal for insulation, protection, and fixation in demanding applications.
Q2 What voltage resistance does Mylar tape offer?
Depending on the model, Mylar tape offers voltage resistance ranging from 3.0 KV to 6.2 KV. For example, the HY100 series (0.06 mm thickness) provides 4.2 KV, while the thicker HY100-B series (0.08 mm) offers up to 6.2 KV, meeting the requirements of various electrical insulation grades.
Q3 Is Mylar tape suitable for use in high-temperature processes like reflow soldering?
Yes. Thanks to the inherent heat resistance of the PET carrier and acrylic adhesive, Mylar tape can withstand the elevated temperatures encountered in reflow soldering and wave soldering processes, making it a reliable choice for PCB manufacturing and electronic assembly applications.
Q4 What colors are available for Mylar tape?
Mylar tape is available in a wide range of colors including Yellowish, Deep Yellow, Blue, Red, Green, Black, White, and Transparent. This variety allows for easy color-coding and identification in complex wiring harness and electronic assembly applications.
Q5 Can Mylar tape be used in lithium battery and energy storage systems?
Absolutely. Mylar tape is widely used in lithium battery cell manufacturing for tab insulation, cell-to-protective-plate insulation, and surface protection. Flame-retardant versions are also available for energy storage systems, helping to enhance the overall safety of battery packs.
Q6 How does Mylar tape compare to 3M polyester film tape products?
Several models in the HY100 series are designed as direct equivalents to well-known 3M products. For instance, HY100-1 is equivalent to 3M 1350F-1Y, HY100-7 to 3M 1350F-1W, and HY100-8 to 3M 1350F-1BL, offering comparable performance and specifications at a competitive price point.
