3M 7000049126 Vibration Damping Foil Tape 436 Silver 6in 36yd

Product Description

The 3M 7000049126 is a dead-soft aluminum foil vibration damping tape designed to absorb and dissipate mechanical vibration while reducing structure-borne noise. The silver foil constraining layer is coated with a viscoelastic acrylic pressure-sensitive adhesive and supplied on a blue polyethylene easy-release liner. The roll measures 6 inches wide by 36 yards long, making it suited for wide-surface damping applications. Installers in HVAC, appliance service, aerospace, automotive, and general industrial maintenance use this tape to quiet panels, housings, ductwork, and other vibrating metal or composite surfaces.

This tape is well suited for residential and commercial HVAC duct systems, appliance cabinets, mechanical enclosures, and industrial equipment panels where vibration transmission and radiated noise are concerns. Its linered construction supports die-cutting for custom shapes, which is useful in manufacturing and fabrication environments. The tape performs across a wide temperature range, tolerating cold-temperature exposure down to -76 degrees F, which makes it a viable choice for refrigeration enclosures, outdoor mechanical equipment, and cold-storage applications.

Key Features

• Dead-soft aluminum foil constraining layer absorbs and dissipates vibration energy
• Viscoelastic acrylic pressure-sensitive adhesive converts vibrational energy to low-level heat
• Cold temperature resistance rated to -76 degrees F for refrigeration and outdoor use
• Resists weather and UV degradation for demanding indoor and outdoor environments
• Linered blue polyethylene release liner enables die-cutting and precise fabrication
• 6-inch width covers large surface areas with fewer overlapping passes

Compatibility

Designed for vibration damping and noise reduction on metal panels, ductwork, appliance housings, and mechanical enclosures across aerospace, automotive, construction, appliance, and MRO applications.

Installation Notes

Clean and dry the target surface thoroughly before application to ensure full adhesive contact. Power down or de-energize any equipment before applying tape to moving or electrically active assemblies. Peel the blue polyethylene liner at a consistent angle and press the tape firmly into place, working from one edge to eliminate air pockets. For die-cut applications, cut on a clean flat surface using standard rotary or steel-rule tooling.
