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.

How quickly will I receive a reply to my request?

Our sales engineers reply to product, catalog and sample requests within 24 hours, including technical data sheets and recommendations for your application.

📡 Electromagnetic Shielding & Anti-Interference

●

Electronic equipment shielding: Used for internal shielding of electronic products such as mobile phones, notebook computers, tablet computers, GPS navigators, etc., to wrap the motherboard, cable or specific components to prevent electromagnetic wave leakage or external interference.

●

Communication equipment: Used to shield cavities and connection gaps in communication equipment such as base station antennas, routers and set-top boxes to ensure stable signal transmission.

⚡ Circuit Conduction & Grounding

●

Circuit board (PCB) patching: In PCB manufacturing or maintenance, it is used to repair broken circuit lines and realize temporary or permanent conduction instead of welding.

●

Flexible circuit board (FPC): Used for conductive connection, lead-out or as a part of the circuit of FPC.

●

Electrical grounding: Used for grounding the metal shell of household appliances and office equipment to prevent static electricity accumulation or leakage.

🔋 Lithium Battery Manufacturing (New Energy)

●

Battery cell connection: Used for the connection between the tab and the protection plate or the parallel/series conductive connection between batteries in the PACK process of lithium batteries (such as power batteries and energy storage batteries).

●

Busbar: Replacing part of metal bus bar, used for current collection and transmission in battery module.

⚙️ Transformer & Motor Manufacturing

●

Transformer winding: Used for winding production of high-frequency transformers and pulse transformers, and the winding density is improved by using its thin characteristics.

●

Motor commutator: In some micro-motors, it is used to connect the conductive strips of the commutator.

🌡️ Heat Dissipation & Heat Conduction

●

LED lighting: Used for the heat conduction connection between the high-power LED lamp beads and the heat dissipation aluminum substrate, which helps to conduct heat quickly.

●

Power device: Used for auxiliary heat dissipation of heating elements such as CPU, graphics card chip and power module.

🌿 Family Gardening & Potted Plant Protection

●

Protection of potted plants: This is the most common application scenario. Stick the copper foil adhesive tape around the edge of the pot mouth or the middle and upper part of the outside of the pot wall. When snails try to climb into the feeding leaves along the basin wall, they will feel uncomfortable when they touch the copper belt, thus protecting potted flowers, herbs and vegetables indoors and outdoors.

🏭 Other Industrial Applications

●

Electromagnetic induction: Used for making induction coil of induction cooker panel, or as trigger element of induction switch.

●

Architecture and decoration: Used for metal decorative lines in high-grade decoration, edge sealing of furniture or as conductive tape for floor heating system.

❓ Frequently Asked Questions (FAQ)

Q1 What is copper foil tape used for?

Copper foil tape is used across a wide range of industries including electronics, communication, new energy, and home gardening. Its primary applications include electromagnetic shielding, PCB circuit repair, lithium battery connections, heat dissipation, transformer winding, and protecting potted plants from snails and slugs.

Q2 What is the difference between single-guided and double-guided copper foil tape?

Single-guided copper foil tape has conductive adhesive on one side only, making it suitable for standard shielding and grounding applications. Double-guided copper foil tape has conductive adhesive on both sides, allowing electrical conductivity through the tape itself — ideal for applications requiring conductivity from both surfaces, such as FPC connections and battery modules.

Q3 What type of adhesive is used on copper foil tape?

Our copper foil tape uses oily acrylic glue, which provides strong adhesion, good temperature resistance, and reliable long-term bonding performance across various surfaces including metals, plastics, and PCB substrates.

Q4 Is the copper foil tape equivalent to 3M products?

Yes, model HY500-3 (0.035mm film thickness, 0.07mm total thickness) is equivalent to 3M1181. Our copper foil tapes are designed to meet or exceed the performance standards of well-known brand equivalents while offering competitive pricing.

Q5 Can copper foil tape be used in lithium battery manufacturing?

Yes. Copper foil tape is widely used in lithium battery PACK processes for tab-to-protection-plate connections and parallel/series conductive connections. It can also replace part of the metal busbar for current collection and transmission in battery modules.

Q6 How do I choose the right thickness of copper foil tape for my application?

The right thickness depends on your specific application. Thinner tapes (e.g., 0.018–0.025mm film thickness) are ideal for flexible circuits and lightweight shielding. Thicker tapes (e.g., 0.050–0.090mm) are better suited for battery connections, busbar replacement, and transformer winding where higher current capacity and mechanical strength are required. Please refer to the specification table above for detailed model options.
