FEATURES:

The sound damping mat is a lightweight, high-grade pure aluminum constrained-layer vibrational damper. conforms with effort to sheet metal and other hard substrates. Material performance in optimized for temperature ranges between 14°F and 140°F (-10°C to +60°C). Material can withstand temperature extremes between -65°F and +350°F (-54°C to +170°C) and is highly resistant to aging.

Acoustic Properties:

 The acoustic loss factor "n" is used as a measure of a material's ability to damp structure-borne sound by stating how much vibrational energy (in steel sheets for instance) is converted to heat rather than sound. For constructions containing several layers of damping material, the combined loss factor "n comb" is used. The theoretical maximum loss factor is 1 (no vibration). An undamped 1mm thick steel panel has a loss factor of roughly 0.001 at 200 Hz. Dynaplate applied to that panel would increase the loss factor to 0.17 @ +20°C (+68°F). Multiple layers of Dynaplate improve sound damping even more.

 Applications:

 Can be die cut to shape and placed onto the body surface directly on painted panels or after the sheet metal is cleaned before painting (typically at the sealer application operation).  is used to treat metal panels, partitions, ducts, doors, bins, panels, and so forth in railroad cars, buses, automobiles, and ships. It is also used for ventilation ducts, relay cabinets, steel furniture, home appliances, sink units, computer equipment, machine tools and many other objects that suffer from vibration-produced noise. 

Installation:

 Use scissors, knife or die to cut the mat to the desired size and shape before removing the release liner. Next, remove dust, grease, moisture, and other foreign matter from the application surface. Peel off the release liner. The simplest application technique is to bend the mat slightly and attach it along its shortest edge. Press the mat firmly into place, using a roller for larger pieces. The roller reduces the risk of leaving air pockets, which reduce sound damping capacity. The temperature of the mat and application surface should not be below room temperature during fitting. Heating the material is not necessary.
