3M 7000049124 Vibration Damping Foil Tape 435 Silver 6 in

Product Description

The 3M 7000049124 is a dead soft aluminum foil vibration damping tape engineered to absorb and dissipate mechanical vibration in demanding industrial and aerospace environments. The aluminum foil constraining layer is coated with a pressure-sensitive viscoelastic acrylic polymer adhesive bonded to an easy-release liner. This construction converts vibrational energy into negligible heat that readily dissipates, reducing noise and material fatigue. The tape measures 6 inches wide and 36 yards long with an 8 mil total thickness. It is rated for use at temperatures as low as -76 degrees F, making it suitable for extreme cold service applications.

This tape is intended for use in aerospace, industrial, and OEM manufacturing environments where vibration damping, noise reduction, and fatigue mitigation are required. The easy-release liner makes it compatible with die-cutting processes, allowing it to be cut to match specific part geometries. It performs reliably in outdoor and exposed environments due to its resistance to UV degradation and weathering. Licensed professionals and OEM fabricators working in aerospace, HVAC duct systems, and heavy equipment manufacturing are the primary installers of this product.

Compatibility

Designed as an OEM-style vibration damping solution for aerospace, industrial fabrication, and HVAC applications requiring a pressure-sensitive foil tape with low-temperature performance.

Installation Notes

This tape is applied by trade professionals and OEM fabricators; surface preparation is critical for maximum adhesion — clean surfaces of oil, dust, and moisture before application. Power down or de-energize any associated equipment before applying tape to mechanical assemblies. When die-cutting, use appropriate cutting tools rated for foil materials. Follow all applicable workplace safety and aviation maintenance regulations when using this product in aerospace applications.
