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.

Bundling and Temporary Fixing of Wire Harness

Glass fiber adhesive tape is soft, easy to stretch and good to fit, which is very suitable for bundling, branch fixing and temporary fixing of wire harness.

Internal wiring harness arrangement of household appliances
Automotive wiring harness bundling and fixing
Internal connecting wires of electronic equipment

⚡

Light Insulation and Winding

Due to the light and thin material, fiberglass tape is suitable for insulation scenes sensitive to thickness, such as:

Lightweight insulation of small motor coil
Auxiliary insulation of inductors and transformers
Insulation winding of electronic components

🔋

Lightweight Wrapping of Lithium Battery Core and Module

In the manufacture of lithium batteries, glass fiber tape is often used for:

Light packing on the surface of battery core
Temporary fixation between battery core and protective plate
Bundling and insulation of wire harness inside module

Its thin and light characteristics will not increase the extra thickness of the battery cell, and it is suitable for designs with high space requirements.

🛡️

Temporary Fixation and Shielding in Electronic Manufacturing

Glass fiber tape can be used in SMT and PCB processes:

Temporary fixing of flexible circuit board (FPC)
Masking areas that do not need to be tinned or sprayed
Temporary protection in manufacturing process

? Frequently Asked Questions

Q: What is the main difference between HY430-1 and HY430-2 fiberglass tape?

HY430-1 uses a standard fiber glass carrier with a thickness of 0.17mm, while HY430-2 uses a mesh polyester fiber carrier at 0.20mm thickness and offers a slightly higher tensile strength of 850 vs 800. HY430-1 is also equivalent to 3M898.

Q: What is the heat resistance range of most fiberglass tape models?

Most models (HY430-1 through HY430-4) are rated for a heat resistance range of -20℃ to 80℃. HY430-5 is rated -10℃ to 80℃, and HY430-6 is rated -5℃ to 70℃.

Q: Is fiberglass tape suitable for use in lithium battery manufacturing?

Yes. Fiberglass tape is widely used in lithium battery manufacturing for light surface packing of battery cores, temporary fixation between battery cores and protective plates, and bundling of wire harnesses inside modules — all without adding significant thickness.

Q: Can fiberglass tape be used in SMT and PCB production processes?

Yes. Fiberglass tape is suitable for SMT and PCB processes, including temporary fixing of flexible circuit boards (FPC), masking areas that should not be tinned or spray-coated, and providing temporary protection during the manufacturing process.

Q: What is the difference between non-residual and residual glass fiber tape (HY430-5 vs HY430-6)?

HY430-5 is a non-residual glass fiber tape (0.14mm thick, rated -10~80℃), meaning it leaves no adhesive residue upon removal. HY430-6 is a residual glass fiber tape (0.15mm thick, rated -5~70℃), which may leave some adhesive. The choice depends on whether a clean removal is required after use.

Q: Which industries commonly use fiberglass tape?

Fiberglass tape is widely used across electronics, electrical engineering, new energy (especially lithium battery manufacturing), automotive, and industrial manufacturing industries — wherever heat resistance, insulation, high tensile strength, and chemical resistance are required.
