3M(TM) Damping Foil 2552 Silver, 2 in x 36 yd 10.0 mil, 5 per case Bulk 3M(TM) Damping Foil 2552 Silver, aluminum foil constraining layer coated with a pressure-sensitive viscoelastic polymer on a poly-coated paper easy-release liner. 3M(TM) Damping Foil Tape 2552 helps damp vibrations on metal and plastic surfaces vibrating at their natural (resonant) frequency, consists of a pressure-sensitive viscoelastic polymer and aluminum foil constraining layer that effectively converts vibrational energy to negligible heat to reducing irritating noises and decreasing wear and tear on parts. Optimal temperature range from 32°F to 140°F (0°C to 60°C).
