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?

📡 Electromagnetic Shielding and 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 and 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 and 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 and 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 and 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

Q1 What is the difference between single-sided and double-sided conductive copper foil tape?

Single-sided conductive copper foil tape (single-guided) has adhesive on one side only, making it ideal for surface mounting and shielding applications where only one conductive face is needed. Double-sided conductive copper foil tape (doubled-guided) conducts electricity through both the top copper surface and the adhesive layer, enabling electrical contact on both sides — commonly used in grounding, PCB repair, and battery connections.

Q2 What type of adhesive is used in your copper foil tape, and is it safe for electronics?

Our copper foil tapes use oily acrylic adhesive, which provides strong, long-lasting bonding while remaining safe for use in electronics environments. The acrylic adhesive offers excellent heat resistance, chemical stability, and reliable adhesion to PCBs, metal surfaces, and flexible substrates without causing corrosion.

Q3 Which model is equivalent to 3M 1181 copper foil tape?

Model HY500-3, which features a film thickness of 0.035mm and a total thickness of 0.07mm, is equivalent to the 3M 1181 copper foil tape. It is a single-sided conductive tape suitable for EMI shielding, grounding, and PCB repair applications.

Q4 Can copper foil tape be used in lithium battery pack (PACK) manufacturing?

Yes. Copper foil tape is widely used in lithium battery PACK processes for tab-to-protection-board connections and parallel/series conductive connections between cells. It can also partially replace metal busbars for current collection and transmission within battery modules, offering a lightweight and flexible alternative.

Q5 What thicknesses are available, and how do I choose the right one?

Our copper foil tapes range from 0.05mm to 0.2mm in total thickness. Thinner options (e.g., HY500-1 at 0.05mm) are ideal for precision electronics and flexible circuits where minimal profile is critical. Thicker variants (e.g., HY500-9 at 0.2mm total) are better suited for applications requiring higher current capacity or more robust mechanical connection, such as transformer windings or battery busbars.

Q6 Is copper foil tape effective for garden pest control, and how should it be applied?

Yes, copper foil tape is a popular and chemical-free method for protecting potted plants from snails and slugs. Simply wrap the tape around the rim or the outer wall of the pot. When snails or slugs come into contact with the copper surface, they experience a mild discomfort that deters them from crossing, effectively protecting your indoor and outdoor plants, herbs, and vegetables without any harmful chemicals.
