Key performance parameters (must be considered when purchasing)Adhesion/Peel Strength: Measuring how "sticky" it is. The commonly used units are N/25mm or N/in. There is a distinction between "initial adhesion force" and "final adhesion force". The selection should be based on the surface material of the adhesive (such as plastic, glass, metal, painted surface).Thickness: ranging from ultra-thin 0.025mm, common 0.05mm, 0.1mm to thicker ones above 0.2mm. Thickness affects the ability to fill gaps, flexibility, and final product thickness.Temperature resistance range:Conventional type: Long term tolerance to -10 ℃~80 ℃.High temperature resistant type: using special acrylic adhesive, it can withstand -20 ℃~120 ℃ for a long time and 150 ℃ or more for a short time (such as SMT reflow soldering process).Substrate type:Transparent PET: the most versatile.White/Black PET: Provides shading, enhances aesthetics, or achieves specific visual effects.Adhesive type:Solvent based acrylic adhesive: With strong comprehensive performance, it is the mainstream.Water based acrylic adhesive: more environmentally friendly, with low VOC.Hot melt adhesive type: It sticks quickly at the beginning, but its temperature resistance is usually poor.Release paper/film: protective adhesive layer. The release force can be classified as light, medium, or heavy, which affects the ease of peeling during automatic mounting.4. Difference from VHB tape (foam double-sided tape)Often mentioned together, but with different purposes:Characteristics: High viscosity PET double-sided tape VHB tapeDense PET film with acrylic foam as the substrateCore features: ultra-thin, high-strength, high viscosity, stable size, extremely thick, high viscosity, cushioning, sealing, filling gapsThickness usually ≤ 0.2mm, usually 0.4mm~2.0mm+Main functions include precise positioning, thin pasting, insulation structure bonding, shock absorption, sound insulation, sealing, and filling uneven surfacesAnalogous application of "industrial adhesive tape" - used for fine fixation of "industrial solder joints" - used for heavy-duty bonding and sealingSimply put, PET double-sided tape is used for flat bonding that requires "thin and strong" properties; VHB is used for structural adhesives that require thickness and toughness, gaps, or buffering.5. Selection and usage suggestionsClear requirements:What material should be glued? (Surface energy is key, plastic parts are difficult to stick)What is the temperature? (SMT process must select high-temperature reflow soldering models)How thick is needed? Do you need shading?Is it permanent or removable? (There are specialized models for removable low residue adhesive)Surface treatment: Before pasting, it is necessary to clean and dry the adhered surface (wipe with IPA), which is the first and most critical step to ensure the bonding effect.Pressure and time: Apply sufficient and uniform pressure (such as rolling with a roller) after pasting, and let it stand for a period of time (usually 24-72 hours) to achieve maximum adhesion.Testing: Before conducting large-scale applications, it is necessary to conduct small-scale bonding tests and aging tests (such as high temperature and humidity, cold and hot cycles) to verify reliability.Famous brands: 3M (with highly renowned series such as 9448A and 55236), Tesa, Nitto (Nitto), Desa, Siwei, etc. They provide detailed technical parameter tables.Summary: High adhesive PET double-sided tape is an indispensable "precision bonding solution" in modern manufacturing, especially in the field of consumer electronics.

Confirm that the surface energy of two materials (such as painted metal glass and plastic wall) directly affects the bonding effect.Evaluate the usage environment:Indoor or outdoor? Outdoor use must choose acrylic adhesive with excellent weather resistance.Are there any drastic temperature changes, ultraviolet radiation, humidity, or chemicals present?Is there continuous vibration or impact?Determine key performance requirements:How strong adhesive force is needed? Lightweight decoration or heavy-duty structure?How much gap do I need to fill? Select the appropriate thickness of foam based on the unevenness or tolerance of the bonding surface.Do you need any special features? Such as flame retardancy, thermal conductivity, and electrical conductivity.Surface treatment: crucial! Ensure that the adhered surface is clean, dry, free of oil, dust, and rust. The best cleaning effect is achieved using isopropanol (IPA).Construction pressure and time: After pasting, sufficient pressure (such as compacting with a roller) should be applied to ensure that the tape is in full contact with the surface. The adhesive strength will reach its maximum value over time (usually 24-72 hours).Test first: Before large-scale application, it is necessary to conduct small sample testing in real materials and environments to verify long-term reliability.5、 The core difference from PET double-sided tapeCharacteristics: Acrylic foam double-sided tape, PET double-sided tapeBase material core elastic foam (three-dimensional structure) hard polyester film (two-dimensional plane)Main functions include filling, buffering, shock absorption, and sealing, while also achieving high initial adhesion and fast bonding on a flat surface with high-strength bonding, and ensuring dimensional stabilityProficient in handling uneven surfaces, tolerances, and shock absorption scenarios, skilled in precise fitting and fixing of smooth and flat surfacesTypical thickness is relatively thick (0.2mm-3.0mm or more) and very thin (0.025mm-0.2mm)Soft to the touch, compressible and hard, incompressibleSummary: PET double-sided tape is like a "tough film", while acrylic foam tape is a "tough sponge". The former is suitable for precise and smooth "surface contact", while the latter is suitable for "body contact" in complex working conditions.summaryAcrylic foam double-sided tape is a revolutionary engineering adhesive material that solves many problems of traditional mechanical fixation and liquid adhesives in terms of shock absorption, sealing, stress management, and construction convenience through its unique "combination of rigidity and flexibility" structure.
