3M 7000048884 Damping Foil Tape 2552 Silver 23.5in X 36yd

Product Description

The 3M 7000048884 is a silver aluminum damping foil tape designed to reduce vibration on metal and plastic surfaces operating at their natural resonant frequency. The construction combines a pressure-sensitive viscoelastic polymer with an aluminum foil constraining layer that converts vibrational energy into low-level heat, effectively deadening surface noise and resonance. The tape ships on a poly-coated paper easy-release liner for clean, controlled application. At 10.0 mil total thickness, it delivers meaningful constrained-layer damping in a roll format suited for industrial, HVAC, and mechanical system applications.

This damping foil is used wherever metal panels, ductwork, equipment housings, or plastic enclosures generate unwanted resonance or vibration noise. Common installation scenarios include HVAC sheet metal duct lining, automotive-style panel damping, compressor housings, and mechanical equipment covers. The roll format at 23.5 inches wide and 36 yards in length is suited for high-volume or large-surface applications where coverage efficiency matters. Installation is handled by mechanical technicians, sheet metal workers, and HVAC professionals working with vibrating surfaces in both residential and commercial settings.

Key Features

• Constrained-layer damping construction using viscoelastic polymer bonded to aluminum foil constraining layer
• Pressure-sensitive adhesive system requires no heat activation for bonding to metal and plastic substrates
• 10.0 mil total tape thickness for effective resonance damping on panel surfaces
• 23.5 inch width and 36 yard length per roll allows efficient coverage of large surface areas
• Poly-coated paper easy-release liner for clean, accurate placement during application
• Silver aluminum face provides a clean finished appearance on exposed surfaces

Compatibility

Designed as a constrained-layer damping solution for metal and plastic surfaces vibrating at resonant frequency, including sheet metal ductwork, equipment housings, and mechanical panels in HVAC and industrial applications.

Installation Notes

This tape is applied by sheet metal workers, HVAC technicians, and mechanical installers. Power down or de-energize any equipment before applying tape to moving or vibrating components. Surfaces should be clean, dry, and free of oils or loose material before application to ensure full adhesive contact. Cut tape to length using a sharp utility knife or shears rated for foil materials.
