Premium 7.5 mil silver aluminum foil vibration damping tape with viscoelastic polymer adhesive, extreme cold temperature resistance to -76°F, weather and UV resistant for aerospace and industrial applications
3M™ Vibration Damping Tape 434 is a premium low-temperature, silver, dead soft aluminum foil tape engineered for industrial applications requiring superior vibration and noise reduction. This 7.5 mil thick tape features a constraining layer coated with a pressure-sensitive viscoelastic polymer adhesive on a blue polyethylene easy-release liner, designed to absorb and dissipate vibration while reducing structure-borne noise and fatigue in metal and composite panels. The tape's viscoelastic acrylic polymer adhesive is specifically optimized to convert vibrational energy into negligible heat that readily dissipates, making it ideal for demanding aerospace, automotive, construction, appliance, and MRO (Maintenance, Repair, and Operations) industries. With its exceptional cold temperature resistance down to -76°F (-60°C), this tape maintains consistent performance in extreme environmental conditions. The linered construction provides die-cutting capabilities for custom applications, while its weather and UV-resistant properties ensure long-term durability in challenging outdoor and industrial environments. Each case contains 9 rolls of 1-inch width by 60-yard length, meeting FAR 25.853(a) requirements for aerospace applications.
