High density double sided tape is engineered for industrial-grade permanent bonding applications requiring exceptional tensile strength and environmental resistance. Available in five specialized widths (5mm, 8mm, 9mm, 12mm, and 25mm), this strongest waterproof double sided tape features a cross-linked polyethylene foam core and high-performance acrylic adhesive system that replaces mechanical fasteners while providing superior vibration damping and waterproof sealing capabilities.
Backed by Jiangsu Gelly Adhesive Material Technology Co., Ltd and our 30 years of adhesive expertise, our High-Density Double Sided EVA Foam Tape is engineered for demanding applications requiring superior cushioning, electrical insulation, and structural bonding. Featuring a high-density, closed-cell EVA (Ethylene-Vinyl Acetate) foam carrier coated on both sides with a super-strong modified acrylic/synthetic rubber adhesive, this tape provides exceptional compression recovery and shock absorption. Its inherent electrical insulation properties and waterproof sealing capabilities make it the ultimate choice for electronics assembly, automotive interior damping, and heavy-duty industrial gasketing.
High-Density Compression Recovery: The high-density closed-cell EVA structure offers superior support and dimensional stability. It resists permanent deformation (compression set) under continuous pressure, ensuring long-lasting cushioning and sealing.
Excellent Electrical Insulation: EVA foam is inherently non-conductive and provides excellent dielectric strength, making it safe and reliable for insulating and securing internal electronic components, batteries, and wire harnesses.
Super Strong Adhesion: Coated with an aggressive modified adhesive, it delivers ultra-high initial tack (quick grab) and permanent holding power, securely bonding to a wide variety of surfaces including rough and irregular substrates.
Outstanding Shock Absorption & Damping: Effectively absorbs impacts, vibrations, and acoustic noise, protecting delicate components from mechanical shock and eliminating rattling in automotive and appliance assemblies.
Weatherproof & Chemical Resistant: The closed-cell structure creates an impenetrable barrier against moisture, dust, and UV radiation, while resisting mild chemicals, plasticizers, and temperature fluctuations.
Electronics & Battery Packs: Insulating, cushioning, and securing lithium-ion battery cells, PCB boards, and delicate sensors within electronic enclosures.
Automotive NVH (Noise, Vibration, and Harshness): Damping vibrations and preventing rattling between interior trim panels, door cards, and dashboard components.
Heavy-Duty Nameplates & Signage: Permanent mounting of heavy metal or plastic logos and nameplates onto textured or powder-coated surfaces.
Construction & HVAC Gasketing: Creating durable, weather-tight seals around windows, doors, and air conditioning units to prevent air/water infiltration.

Our AdvantagesOur Advantages
A Strong and Established Tape Manufacturer
Standard PE foam is softer, lighter, and more cost-effective, making it suitable for basic cushioning and lightweight packaging. High-Density EVA foam has a much tighter, denser closed-cell structure. This provides superior compression recovery (it bounces back after being squashed), higher tensile strength, better thermal insulation, and excellent electrical dielectric properties, making it the premium choice for structural mounting, electronics insulation, and automotive NVH damping.
Yes. EVA (Ethylene-Vinyl Acetate) is inherently non-conductive and provides excellent electrical insulation. It is widely used in the new energy and electronics industries to insulate, cushion, and secure lithium-ion battery cells, PCB boards, and delicate sensors, preventing short circuits while protecting components from mechanical shock and vibration.
This tape is engineered for permanent structural bonding and heavy-duty mounting. The aggressive modified adhesive is designed to create a long-lasting, weather-proof seal. If removal is necessary after full cure, it may require mechanical scraping or the use of a commercial adhesive remover (like citrus-based solvents or IPA), and it may damage delicate surfaces like painted drywall. For temporary or removable applications, please request our low-tack series.
Absolutely. We offer a full thickness range from 0.5mm up to 5.0mm (and thicker upon request). We utilize precision die-cutting and kiss-cutting equipment to supply your EVA foam tape in custom 2D shapes, gaskets, and pads, perfectly tailored to your assembly drawings for electronics and automotive applications.
