Polyimide tape (often called Golden Finger Tape) is the core category of special adhesive products, with high temperature resistance, acid and alkali resistance and strong insulation, which is suitable for high-end manufacturing scenes and meets the high requirements of special adhesives. Its uses cover many core fields such as electronics and new energy. The specific categories are as follows:
⚡ Electronic and Electrical Industry (Core Application Field)

This is the main use of polyimide tape, which adapts to the strict requirements of precision electronic manufacturing, especially to the processing requirements of high-end electronic components.

Circuit Board (PCB) Processing

The core is used for gold finger protection. After the plug-in end (gold finger) of the circuit board is plated with gold/tin, adhesive tape is applied to prevent corrosion and contamination during welding and electroplating. After welding, no residual glue can be easily peeled off, which is necessary for PCB process. At the same time, it can be used for local shielding protection during wave soldering and reflow soldering of circuit boards.

Insulation and Fixation of Electronic Components

Adapts to resistors, capacitors, inductors, chips and other components for pin insulation and solder joint shielding to avoid short circuit. It can also fix electronic flat cables and wire harnesses, resistant to high temperature and does not release harmful substances, suitable for internal wiring of high-end electronic equipment.

Lithium Battery Manufacturing

In the processing of soft-package lithium batteries and cylindrical lithium batteries, it is used for battery lug insulation and battery wrapping and fixing, which can withstand the high-temperature process when battery is packaged, and has the characteristics of electrolyte corrosion resistance to ensure the safety and stability of batteries.

High-Temperature Electronic Process Shielding

When spraying, baking and sandblasting electronic components, it is used to shield and protect the parts that do not need to be treated. It can withstand high temperature, and there is no residual glue and no damage to the substrate after shielding.

🌱 New Energy Industry (High-Growth Application Field)

Meet the high requirements of the new energy industry for temperature resistance, weather resistance and insulation, and adapt to the manufacture of high-end new energy products.

Photovoltaic Module

Used for shielding protection when photovoltaic cells are welded in series, resistant to high-temperature welding process, ultraviolet rays and high-low temperature cycles, so as to meet the long-term use requirements of outdoor photovoltaic modules. It can also be used for insulation and sealing assistance of assembly frame and junction box.

New Energy Vehicles

Used in on-board motors and electronic control systems for line insulation and high-temperature component protection. Inside the power battery pack, it is used for insulation and isolation between batteries and modules, and can withstand the high and low temperature and vibration environment when the car is driving.

Hydrogen Energy Equipment

Used for shielding and insulation in high-temperature process when the core components of fuel cell are processed, which can withstand the corrosion of hydrogen environment and ensure the stability of the equipment.

🏭 Industrial Manufacturing and Processing Field

Suitable for all kinds of industrial high-temperature processes, with strong universality and customization requirements.

Metal Processing

When metal parts are sprayed, electrophoresed and electroplated at high temperature, they are used for shielding and protecting the non-processed surfaces, which can withstand high temperature and do not react with metal substrates. It can also be used for surface protection of metal stamping and bending to prevent scratching.

Processing of Plastics and Composite Materials

When high-temperature resistant plastics and carbon fiber composite materials are molded, they are used for mold shielding and product positioning. Can withstand high molding temperature, and there is no residual glue after peeling to ensure the surface smoothness of products.

High-Temperature Baking and Curing

Used to cover the parts that don't need curing in the high-temperature baking and curing process of various products (such as hardware, plastics and coatings), and can withstand the high temperature and adapt to different baking processes.

🔬 Other Niche High-End Uses
Semiconductor Manufacturing

Used for wafer surface shielding and pin insulation in semiconductor wafer cutting and packaging processes, which can withstand high packaging temperature and has high cleanliness without dust pollution.

Medical Equipment

Used in high-end medical instruments (such as high-temperature sterilization equipment and precision diagnostic instruments) to insulate and fix internal electronic components, which can withstand high-temperature sterilization process and meet medical-grade environmental protection standards.

High-Temperature Label Substrate

Some polyimide tapes can be used as high-temperature resistant label substrate for labels that need to be kept in high-temperature environment for a long time (such as engine and boiler parts).

🌟 Core Characteristics Support: Wide temperature range, excellent insulation, acid and alkali resistance / salt fog / ultraviolet resistance, peeling without residual glue — benchmarking international similar high-end products.

⚙️ Customized Adaptation: Products with different thickness, viscosity and temperature resistance can be customized according to the needs of different industries to adapt to different processes and scenarios. At the same time, they have cost advantages and cost performance ratio is higher than that of international brands.

❓ Frequently Asked Questions
Q What is polyimide tape and why is it called "Golden Finger Tape"?
Polyimide tape is a high-performance adhesive tape made from polyimide film coated with silicone or acrylic adhesive. It is commonly called "Golden Finger Tape" because one of its primary uses is protecting the gold-plated connector edges (gold fingers) on circuit boards (PCBs) during electroplating and soldering processes. Its golden-amber color also contributes to this nickname.
Q What is the maximum temperature resistance of polyimide tape?
All models in the HY200 series offer a temperature resistance of up to 260°C (500°F). This makes polyimide tape suitable for demanding high-temperature manufacturing processes such as reflow soldering, wave soldering, high-temperature baking, and photovoltaic cell welding.
Q Will polyimide tape leave residue after removal?
No. One of the key advantages of polyimide tape is its clean removal capability. After use — even after exposure to high temperatures — it peels off cleanly without leaving adhesive residue on the substrate surface. This is critical for PCB gold finger protection, semiconductor shielding, and precision industrial processes where surface cleanliness is essential.
Q How do I choose the right model of polyimide tape for my application?
Selection depends on several factors: (1) Film thickness — thinner films (0.015–0.025mm) are suitable for fine PCB work, while thicker films (0.075–0.125mm) provide stronger mechanical protection; (2) Adhesion strength — choose based on required bonding force to your substrate; (3) Elongation at break — higher elongation suits curved or irregular surfaces; (4) Equivalent standard — if you need to replace 3M products (e.g., 3M98C-1, 3M7413D), refer to the equivalent column in the spec table above.
Q Is polyimide tape suitable for use in lithium battery and new energy vehicle manufacturing?
Yes. Polyimide tape is widely used in lithium battery manufacturing for battery lug insulation, cell wrapping, and module isolation within power battery packs. It withstands the high-temperature packaging processes and resists electrolyte corrosion. In new energy vehicles, it is also used for insulation in on-board motors and electronic control systems, as well as thermal and vibration management within battery modules.
Q Can polyimide tape be customized for specific industrial requirements?
Yes. Polyimide tape can be customized in terms of film thickness, adhesive viscosity, total thickness, and temperature resistance level to meet the specific requirements of different industries and processes. Custom widths and lengths are also available. Compared to international brands, customized polyimide tape products offer a higher cost-performance ratio while maintaining equivalent quality standards.
