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.

The application of VHB double sided tape in industrial field is very mature. It is not only a kind of "viscose", but also a structural bonding material. In the industrial scene, VHB double sided tape is often used to replace traditional mechanical connection methods such as screws, rivets and welding, so as to realize lightweight, aesthetic and efficient production.

Automobile Manufacturing Industry

Body Exterior Trim Assembly

Applications

Side skirts, wheel eyebrows, window trims, luggage racks, spoilers (tails), license plate frames, and door bumper strips.

💡 Industrial Value: Traditional buckles or screws are easy to produce wind noise and vibration when driving at high speed. VHB tape can provide buffer and eliminate noise, and the installation speed is several times faster than drilling.

Window & Glass System

Applications

Windshield decorative strip, skylight frame sealing, rearview mirror base fixing.

💡 Industrial Value: Excellent weather resistance — will not age and fail under exposure and rain, and can bear the difference of thermal expansion coefficient between glass and metal.

Automobile Interior Trim Fixing

Applications

Instrument panel assembly, door trim, column trim (A/B/C column), sound insulation cotton, airbag cover.

💡 Industrial Value: Bonds different materials (such as ABS plastic and metal), and will not produce volatile compounds (VOCs) like glue — meets environmental protection standards in the car.

Batteries & New Energy Components

Applications

Fixing the insulation sheet and heat sink of power battery pack, binding and fixing the battery module.

💡 Industrial Value: High temperature resistance, flame retardant (specific model), and good cushioning performance — protects the battery from road vibration impact.

Electronics & Electrical Appliance Manufacturing Industry

Consumer Electronics (Mobile / PC / Tablet)

Applications

Screen assembly: Bonding between touch screen and middle frame (black VHB prevents light leakage).
Battery fixing: Fix the lithium battery inside the fuselage to prevent shaking.
Camera module: Fixing of lens and PCB.
Waterproof & dustproof: Acts as a gasket, filling the gap of the fuselage.

💡 Industrial Value: Ultra-thin thickness (as thin as 0.2mm), without occupying internal space. High adhesive strength prevents the screen from separating when falling.

White Goods (Home Appliances)

Applications

Refrigerator door seal
Washing machine control panel
Air conditioning air outlet grille
TV frame and backplane connection

💡 Industrial Value: Wide temperature range — adapts to the low temperature inside the refrigerator and the vibration of the washing machine motor.

Frequently Asked Questions (FAQ)

Q What is VHB double sided tape and how is it different from regular adhesive tape?

VHB (Very High Bond) double sided tape is a high-performance structural bonding material made with a high-strength acrylic adhesive core. Unlike regular adhesive tape, VHB tape can replace mechanical fasteners such as screws, rivets, and welds, offering a strong, durable, and clean bond between two surfaces. It provides excellent resistance to temperature, solvents, and vibration.

Q What thickness of VHB tape should I choose for my application?

The ideal thickness depends on your specific use case. Thinner tapes (0.25mm–0.64mm) offer higher tensile strength and are ideal for smooth, rigid surfaces such as metal panels and electronic assemblies. Thicker tapes (1mm–3mm) provide better gap-filling, cushioning, and vibration absorption, making them suitable for uneven surfaces or applications requiring flexibility, such as automotive body trim and battery module bonding.

Q Is VHB tape suitable for outdoor and high-temperature environments?

Yes. All HY980 series VHB tapes offer temperature resistance of ≥120℃ and high solvent resistance. The acrylic-based adhesive is UV-stable and weather-resistant, making it well-suited for outdoor applications such as automotive exterior trim, window sealing, and signage. It will not degrade, yellow, or lose adhesion under prolonged exposure to sunlight and moisture.

Q Can VHB tape bond different types of materials together?

Yes. VHB double sided tape is designed to bond dissimilar materials, including metal, glass, ABS plastic, polycarbonate, painted surfaces, and composites. This makes it especially valuable in automotive interiors where components like ABS plastic panels must be bonded to metal frames, and in electronics where different substrates need to be joined without the use of mechanical fasteners or liquid adhesives.

Q Which HY980 model is equivalent to 3M VHB tapes?

The HY980 series provides direct equivalents to a wide range of 3M VHB products. For example, HY980-1 (Black, 0.64mm) corresponds to 3M 4939/5925; HY980-9 (Grey, 1.2mm) corresponds to 3M 4941/4611/4211/5344; and HY980-19 (White, 3mm) corresponds to 3M 4959/5359. Please refer to the full specification table above for a complete list of 3M equivalent models.

Q How long does VHB tape hold, and can it be removed after bonding?

All HY980 series tapes have a hold force of greater than 24 hours under standard test conditions, and in practice the bond is designed to be permanent for most industrial applications. While VHB tape can technically be removed using tools such as a plastic wedge or dental floss combined with isopropyl alcohol, it is engineered for long-term structural bonding and removal may damage the bonded surfaces. It is not recommended for temporary or repositionable applications.
