In industrial bonding scenarios, double-sided tape is gradually replacing traditional fixing methods such as bolts, rivets and welding. Its core value lies in balancing bonding reliability and substrate protection, while simplifying the construction process and improving product appearance integrity. Targeting different bonding needs, LVZHIMEI has created three series of double-sided tapes: tissue paper, PET and foam. By accurately matching substrate characteristics and adhesive formulas, it achieves full-scene coverage from precision electronic component bonding to heavy component fixing, meeting the personalized needs of different industries for bonding strength, weather resistance and concealment.
Tissue paper double-sided tape uses thin tissue paper as the base material, coated with acrylic pressure-sensitive adhesive, with good flexibility and initial adhesion, suitable for light bonding scenarios, such as paper packaging, label pasting, office stationery fixing, temporary positioning of electronic components, etc. LVZHIMEI tissue paper double-sided tape provides three specifications (low, medium and high) according to viscosity requirements. The thin version (thickness ≤0.1mm) is suitable for bonding small parts in precision electronic assembly, such as mobile phone key fixing and temporary fixing of PCB components, and its easy die-cutting feature can accurately match complex shapes; the thick version (thickness 0.15mm-0.3mm) is suitable for paper packaging and decoration scenarios, such as gift box pasting and poster fixing, with no residual adhesive after peeling and no damage to the substrate surface.
PET double-sided tape uses high-strength PET film as the base material, combined with high-performance acrylic or silicone adhesive, with excellent tensile strength, temperature resistance and chemical corrosion resistance, suitable for medium-heavy bonding and special environment scenarios. Among them, acrylic-based PET double-sided tape has a temperature resistance range of -20℃ to 80℃ and bonding strength ≥1.8N/mm, suitable for automotive interior bonding (such as instrument panel decorative parts, door trim panel fixing), building decoration (such as stone, metal plate bonding), electronic equipment shell fixing and other scenarios, which can withstand long-term vibration and temperature fluctuations; silicone-based PET double-sided tape has a temperature resistance range of -50℃ to 200℃, suitable for bonding in high-temperature environments, such as oven inner wall component fixing and electronic equipment high-temperature area assembly, and also has good insulation performance, which can be adapted to electrical component bonding.
Foam double-sided tape uses EVA, PE or PU foam as the base material, with additional functions such as shock absorption, gap filling, sound insulation and heat insulation, suitable for irregular substrate bonding, gap filling and heavy fixing scenarios. LVZHIMEI EVA foam double-sided tape has excellent elasticity, can fill gaps of 0.5mm-5mm, suitable for automotive door and window sealing, building curtain wall sound insulation, home appliance shockproof fixing; PE foam double-sided tape has higher density, better tensile strength and weather resistance, suitable for outdoor advertising fixing, stone curtain wall bonding, heavy equipment shock absorption fixing; PU foam double-sided tape has flame-retardant and waterproof characteristics, suitable for fire-fighting equipment fixing and component bonding in humid environments, such as bathroom decorative part fixing and outdoor lighting equipment installation.
The selection principle should follow "substrate adaptation, strength matching and environment correspondence": tissue paper double-sided tape is preferred for light paper and plastic substrates, PET double-sided tape for medium-heavy metal, glass and PET substrates, and foam double-sided tape for irregular substrates and gap filling scenarios; silicone-based PET double-sided tape is preferred for high-temperature environments, waterproof foam double-sided tape for humid environments, and UV aging-resistant PET or foam double-sided tape for outdoor scenarios. LVZHIMEI can provide customized die-cutting, thickness adjustment and adhesive formula optimization services to help users accurately match scenario needs, replace traditional mechanical fixing methods, and improve construction efficiency and product quality.
