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.

Frequently Asked Questions (FAQ)

Q: What is the maximum heat resistance rating of this glass fabric tape?

Both the single-sided (HY420-1) and double-sided (HY420-2) glass fabric tapes can withstand continuous operational temperatures up to 260℃, making them suitable for severe thermal environments.

Q: What standard international tape models can HY420-1 replace?

Model HY420-1 serves as a high-performance equivalent to mainstream industrial tapes such as 3M 69 and TESA 4618.

Q: What is the difference between HY420-1 and HY420-2?

HY420-1 is a single-sided glass fabric tape with an adhesion strength of 8 N/25mm, whereas HY420-2 is a double-sided tape offering an adhesion rating of 6 N/25mm designed for bonding two surfaces together under high heat.

Q: What is the electrical insulation breakdown performance?

These tapes have a voltage resistance rating of 2.5 KV, providing reliable dielectric barrier protection for motors, transformers, and electronic assemblies.

Q: How is glass fabric tape utilized in PCB and SMT assembly?
