3M Damping Aluminum Foam Sheets 4014 Silver - 18 in x 48 in 250 mil

3M Damping Aluminum Foam Sheet 4014 is a vibration and noise reduction material provided in sheets for excellent per-pound cost ratios. Open cell polyurethane foam with an aluminum-urethane constraining layer absorbs panel vibration and dissipates it to negligible heat, reducing resonant noise and fatigue. Pressure-sensitive adhesive and easy-release liner make for fast, smooth application.
