Do you offer free samples of industrial adhesive tapes?

Yes. Free samples are available for our standard electrical and double-sided tape grades. Share your application, substrate, operating temperature and required width, and our engineers will recommend and prepare suitable grades for testing.

Which certifications do Huayuan adhesive tapes hold?

Our factory has operated an ISO 9001 quality management system since 2013. Selected products are UL certified, the entire range is SGS tested, and all products comply with the EU RoHS directive. Certificates and test reports are available on request.

Can you produce custom widths, colors and die-cut parts?

Yes. We have offered OEM and ODM services since 2007 and expanded into precision die-cutting in 2013. Tapes can be slit to custom widths and lengths, supplied in custom colors or liners, die-cut to drawing and packed under your private label.

How do I choose between polyimide, PET mylar and glass cloth tape?

Choose polyimide tape for the highest heat resistance in thin profiles, such as PCB wave-solder masking and lithium battery insulation. PET mylar tape is the cost-effective choice for transformer and coil insulation at Class B temperatures. Glass cloth tape offers higher tensile strength and abrasion resistance for motor and Class H insulation.

Where are your adhesive tape factories located?

Production is located in Guangdong, China: the Zhuhai factory at Nanping Science and Technology Park and the Zhongshan factory in Tanzhou Town, added in 2025. International business is supported by Huayuan International Technology (Hong Kong) Co., Ltd., established in 2014.

Customizable Specs

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 use is 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 — necessary for PCB process. It can also be used for local shielding protection during wave soldering and reflow soldering.

Frequently Asked Questions (FAQ)

Q What is polyimide tape and why is it called "Golden Finger Tape"?

Polyimide tape is a high-performance adhesive tape made from a polyimide film base coated with a silicone or acrylic adhesive. It is commonly called "Golden Finger Tape" because one of its most well-known uses is protecting the gold-plated contact fingers on PCB circuit boards during electroplating and soldering processes, preventing contamination and corrosion.

Q What is the maximum temperature resistance of polyimide tape?

All models in our polyimide tape range (HY200 series) are rated for continuous use up to 260°C. This makes them suitable for demanding high-temperature manufacturing processes including reflow soldering, wave soldering, high-temperature baking, and semiconductor packaging.

Q Does polyimide tape leave residue after removal?

No. One of the key advantages of polyimide tape is that it leaves no residual glue after peeling, even after exposure to high temperatures. This is critical for applications in electronics, semiconductors and precision manufacturing where surface cleanliness is essential.

Q What industries use polyimide tape most commonly?

Polyimide tape is widely used across several industries, including: Electronics & PCB manufacturing (gold finger protection, component insulation), New energy (lithium batteries, photovoltaic modules, EV battery packs), Industrial manufacturing (metal coating, plastic molding, high-temperature curing), Semiconductors (wafer processing), and Medical equipment (sterilization-resistant insulation).

Q Can polyimide tape be customized in different thicknesses and adhesion levels?

Yes. We offer a wide range of models with film thicknesses from 0.015mm to 0.125mm and total thicknesses from 0.030mm to 0.18mm. Adhesion strength, viscosity and temperature resistance can all be customized to meet the specific requirements of different industries and manufacturing processes.

Q Are your polyimide tapes equivalent to 3M products?

Several models in our HY200 series are direct equivalents to 3M products. 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 with a more competitive cost-performance ratio.
