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 glass cloth adhesive tape made of?

Glass cloth adhesive tape is made from high-strength glass fiber cloth as the backing material, coated with either high-temperature resistant silicone adhesive or acrylic adhesive. This combination provides excellent heat resistance, electrical insulation, and strong mechanical performance.

Q What is the maximum heat resistance of HY420 series glass fabric tape?

Both HY420-1 (single-sided) and HY420-2 (double-sided) glass fabric tapes offer a heat resistance of up to 260°C, making them suitable for demanding high-temperature industrial and electronic applications.

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

HY420-1 is a single-sided glass fabric tape with an adhesion to steel of 8 N/25mm, while HY420-2 is a double-sided glass fabric tape with an adhesion of 6 N/25mm. Both share the same film thickness (0.1mm), total thickness (0.19mm), and tensile strength (380 kg/25mm). The double-sided version is ideal for bonding two surfaces together.

Q Is glass fabric tape suitable for use in lithium battery and new energy applications?

Yes. Glass fabric tape is widely used in the new energy industry, including binding and insulating power battery cells, protecting wiring harnesses in high-temperature zones of battery modules, and providing high-temperature insulation for motors and electronic control systems in electric vehicles.

Q Can glass cloth tape be used during SMT and wave soldering processes?

Absolutely. Glass cloth adhesive tape is commonly used in SMT processes for gold finger shielding when PCBs pass through tin furnaces, high-temperature masking during wave soldering and reflow soldering, and reinforcement of FPC flexible circuit boards.

Q What products are equivalent to HY420-1 glass fabric tape?

HY420-1 glass fabric tape is equivalent to 3M 69 and TESA 4618, which are well-known international standards for high-temperature glass cloth insulation tapes. This makes HY420-1 a reliable and cost-effective alternative for global manufacturing requirements.
