ACOUSTIC PROPERTIES
The acoustic loss factor “n” is used as a measure of ability to damp structure-borne sound. It states 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. Dynamat Xtreme applied to that panel would increase the loss factor to
0.417 @ +20C (+68F). Multiple layers of Dynamat Xtreme can be used to improve sound damping further.
APPLICATIONS
Dynamat Xtreme can be die cut to shape and placed onto the body surface after sheet metal cleaning operation and prior to
paint system (typically at the sealer application operation) or on painted panels. Dynamat Xtreme is used as treatment for metal
panels, partitions, ducts, doors, bins, panels etc. 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 for many other purposes
INSTALLATION
Dynamat Xtreme should be cut to the desired size before the release liner is removed. It may be cut with scissors, knife or die.
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. The mat is then pressed firmly into place,
preferably with a roller for larger pieces. This reduces the risk of leaving air pockets, which reduce the 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
