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.

Copper foil tape is widely used in the fields of electronics, communication, electromagnetic compatibility (EMC) and new energy because of its excellent electrical conductivity, shielding effect and thermal conductivity.

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

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

Single-sided copper foil tape (e.g., HY500-1 to HY500-4) has adhesive on one side only, making it ideal for surface attachment and shielding applications. Double-sided copper foil tape (e.g., HY500-5 to HY500-9) has conductive adhesive on both sides, allowing electrical conductivity through the tape — commonly used in battery connections and grounding applications.

Q What type of adhesive is used in HY500 series copper foil tape?

All models in the HY500 series use oily acrylic glue, which provides strong, long-lasting adhesion across a wide range of surfaces and temperatures. This adhesive type is also resistant to moisture and aging, making it suitable for both indoor and outdoor applications.

Q Which model is equivalent to 3M1181 copper foil tape?

The HY500-3 model is equivalent to 3M1181. It features a film thickness of 0.035mm and a total thickness of 0.07mm, making it a cost-effective alternative with comparable performance for electromagnetic shielding and PCB repair applications.

Q Can copper foil tape be used for lithium battery manufacturing?

Yes. Copper foil tape is widely used in lithium battery manufacturing, particularly in the PACK process for connecting battery tabs to protection plates and for parallel or series conductive connections between cells. It is also used as a busbar replacement for current collection and transmission within battery modules.

Q How does copper foil tape protect potted plants from snails?

When a snail's moist body comes into contact with copper foil tape, a small electrical reaction occurs due to the interaction between the snail's mucus and the copper surface. This creates a harmless but unpleasant sensation for the snail, deterring it from crossing the tape barrier. Simply apply the tape around the rim or outer wall of the pot to protect plants effectively.

Q What tensile strength and elongation does HY500 series copper foil tape offer?

All models in the HY500 series share a tensile strength of 4.5 kg/25mm and an elongation at break of 5–6%. These properties ensure the tape maintains structural integrity during application and under mechanical stress, making it reliable for demanding industrial and electronic uses.
