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:
โšก Electronic and Electrical Industry Core Application

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.

๐Ÿ”Œ Circuit Board (PCB) Processing

Core use for gold finger protection. After the plug-in end is plated with gold/tin, tape is applied to prevent corrosion and contamination during welding and electroplating. After welding, no residual glue โ€” easily peeled off. Also used for local shielding during wave soldering and reflow soldering.

๐Ÿ”ง Insulation & Fixation of Components

Adapts to resistors, capacitors, inductors, chips and other components for pin insulation and solder joint shielding to avoid short circuit. Fixes electronic flat cables and wire harnesses โ€” resistant to high temperature, no harmful substances released.

๐Ÿ”‹ Lithium Battery Manufacturing

Used for battery lug insulation and battery wrapping/fixing in soft-package and cylindrical lithium battery processing. Withstands high-temperature packaging processes; resistant to electrolyte corrosion to ensure battery safety and stability.

๐Ÿ›ก๏ธ High-Temperature Process Shielding

When spraying, baking and sandblasting electronic components, used to shield and protect parts that do not need treatment. Withstands high temperature with no residual glue and no damage to the substrate after shielding.


๐ŸŒฑ New Energy Industry High-Growth 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.

โ˜€๏ธ Photovoltaic Modules

Used for shielding protection when photovoltaic cells are welded in series. Resistant to high-temperature welding, UV rays and high-low temperature cycles for long-term outdoor use. Also used for insulation and sealing of assembly frames and junction boxes.

๐Ÿš— New Energy Vehicles

Used in on-board motors and electronic control systems for line insulation and high-component protection.

๐Ÿ”ฉ Power Battery Packs

Inside power battery packs, used for insulation and isolation between batteries and modules. Withstands high/low temperature and vibration environments during vehicle operation.

๐Ÿ’ง Hydrogen Energy Equipment

Used for shielding and insulation in high-temperature processes when core fuel cell components are processed. Withstands hydrogen environment corrosion to ensure equipment stability.


๐Ÿญ Industrial Manufacturing & Processing

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

โš™๏ธ Metal Processing

When metal parts are sprayed, electrophoresed and electroplated at high temperature, used for shielding and protecting non-processed surfaces. Withstands high temperature without reacting with metal substrates. Also used for surface protection during metal stamping and bending to prevent scratching.

๐Ÿงฑ Plastics & Composite Materials

When high-temperature resistant plastics and carbon fiber composite materials are molded, used for mold shielding and product positioning. Withstands high molding temperatures with no residual glue after peeling to ensure surface smoothness.

๐ŸŒก๏ธ High-Temperature Baking & Curing

โ“ 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 a heat-resistant adhesive. It is commonly called "Golden Finger Tape" because one of its primary applications is protecting the gold finger (connector edge) of circuit boards (PCBs) during the gold/tin plating and soldering process, preventing contamination and corrosion.
Q What is the maximum temperature resistance of polyimide tape?
All models in our polyimide tape series (HY200 range) offer a temperature resistance of up to 260ยฐC. This makes them suitable for demanding high-temperature processes including reflow soldering, wave soldering, high-temperature baking, and semiconductor packaging.
Q Will polyimide tape leave residual glue after removal?
No. One of the key advantages of our polyimide tape is its clean removal property โ€” it leaves no residual glue on the substrate after peeling, even after exposure to high temperatures. This is critical for PCB processing, semiconductor manufacturing, and precision industrial applications where surface cleanliness is essential.
Q What industries are polyimide tapes most commonly used in?
Polyimide tapes are widely used across multiple industries including: electronics and PCB manufacturing (gold finger protection, component insulation), new energy (lithium battery production, photovoltaic modules, EV battery packs), industrial manufacturing (metal processing, composite material molding), semiconductor fabrication, and medical equipment.
Q Can polyimide tape be customized for specific thickness and adhesion requirements?
Yes. We offer a wide range of standard models (film thickness from 0.015mm to 0.125mm, total thickness from 0.030mm to 0.18mm) and can also provide custom products with tailored thickness, viscosity, and temperature resistance levels to meet the specific requirements of different industries and manufacturing processes.
Q How does your polyimide tape compare to international brands like 3M?
Several of our models are direct equivalents to well-known 3M products โ€” for example, HY200-2B is equivalent to 3M 98C-12, HY200-2D is equivalent to 3M 7413D, and HY200-2F is equivalent to 3M 98C-1. Our products offer comparable performance in temperature resistance, insulation, and clean removal, while providing a significant cost advantage over international brands.
