5mm and 10mm strong waterproof double sided tape is specifically engineered for permanent bonding applications; exceptional holding power and various forms of environmental resistance are the primary focuses of its design. Wholesale distributors of products within automotive, construction, and to a point manufacturing, will find this waterproof double tape ideal - demanding conditions are met with consistent, reliable performance.
Backed by Jiangsu Gelly Adhesive Material Technology Co., Ltd and our decades of adhesive expertise, our Strong Waterproof Double Sided Foam Tape is an industrial-grade bonding solution engineered for the most demanding environments. Featuring a high-density, closed-cell PE/EVA foam carrier coated on both sides with a modified acrylic/synthetic rubber adhesive, this tape delivers exceptional bonding performance without the need for mechanical fasteners. Its closed-cell structure ensures absolute waterproofing, while the flexible foam core provides superior vibration damping and gap-filling capabilities, making it the ultimate choice for automotive, outdoor signage, and heavy-duty industrial assembly.
Exceptional Bonding Performance: The industrial-grade acrylic adhesive forms strong, near-permanent bonds between a wide array of materials, eliminating the need for screws, rivets, or welding. Peel strength progressively builds over time for long-term reliability.
Waterproof Closed-Cell Construction: The closed-cell PE/EVA foam structure prevents any form of water absorption (less than 0.01g/cm²), ensuring that wet conditions and high humidity do not compromise bonding performance.
Advanced Weather & UV Resistance: Withstands prolonged outdoor exposure without visible degradation. The tape maintains wide-range temperature resilience from -40°C to +90°C, making it suitable for nearly all global climates.
Vibration Damping & Noise Reduction: The flexible foam core effectively absorbs shock, dampens vibrations, and reduces acoustic noise, which is critical for automotive interiors and heavy machinery.
Superior Gap Filling & Conformability: Compensates for small differences in thermal expansion and conforms perfectly to both smooth and irregular/rough surfaces, ensuring 100% contact area.
Automotive Exterior & Interior: Mounting emblems, nameplates, weatherstripping, and wheel arch trims; dampening vibrations between body panels.
Outdoor Signage & Construction: Permanent bonding of heavy metal or acrylic signs, architectural cladding, and decorative mouldings exposed to rain, wind, and UV radiation.
Electronics & Appliance Assembly: Securing internal components, providing acoustic silencing, and packaging electronic accessories with cushioning protection.
General Industrial Gasketing: Creating watertight seals for enclosures, HVAC systems, and marine applications where moisture ingress must be prevented.

Our AdvantagesOur Advantages
A Strong and Established Tape Manufacturer
Unlike open-cell foams (like standard PU sponge) that act like sponges and absorb water, our tape features a closed-cell PE/EVA foam structure. This means the individual microscopic air pockets within the foam are completely sealed off from one another. This structure prevents any form of water absorption (less than 0.01g/cm²), ensuring that rain, high humidity, and wet conditions do not compromise the tape's structural integrity or bonding performance.
Yes, in many applications. The industrial-grade modified acrylic adhesive provides a high weight capacity and progressive adhesion build (peel strength increases over 24-72 hours). By distributing stress evenly across the entire bonded area—unlike screws which concentrate stress at single points—the tape eliminates the need for drilling holes, prevents rust, and provides a clean, invisible fastening method for nameplates, trims, and signage.
The flexible PE/EVA foam core acts as a shock absorber, effectively dampening vibrations and reducing acoustic noise in automotive and industrial environments. Furthermore, the foam's compressibility allows it to act as a buffer, compensating for small differences in thermal expansion between dissimilar materials (e.g., bonding metal to plastic) without causing the bond to fail or the substrates to warp.
Absolutely. We offer comprehensive customization services. Utilizing high-precision flatbed and rotary die-cutting equipment, we can supply your waterproof foam tape in custom 2D shapes, gaskets, and pads. We can also provide extended release liner tabs (fingers) to make peeling and application incredibly easy for your assembly line operators.
