Description:
Dynaplate is a lightweight, high-grade pure
aluminum constrained-layer vibrational damper.
Dynaplate 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:
Dynaplate 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).
Dynaplate 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 Dynaplate 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 Dynaplate's 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.
