Damping Foil
2552
Technical Data
January, 2012
Product Description
3M™ Damping Foil 2552 consists of a room temperature pressure sensitive
viscoelastic polymer on a dead soft aluminum foil and is
designed for application
to vibrating panels and support members.
The combination of viscoelastic
polymer and an aluminum foil backing (a constrained layer damper, or CLD) has
proved to be a unique construction with exceptional ability to control resonant
vibrations in the temperature range of 32° to 140°F (0° to 60°C), with survivability
from -25° to 175°F (-32° to 80°C).
Typical Damping
Properties
The high-energy dissipative polymer used in 3M damping foil 2552 can afford
excellent control of resonance-induced vibrations. When applied to a vibrating
structure, the polymer used in 3M damping foil 2552 converts vibration to negligible
heat. Vibration amplitudes and structure-borne noise can be consequentially reduced.
The performance of most damping devices is highly dependent on the interaction
between the device and the system to which it is applied. A constrained layer control
system is no different than a typical damping device and its ability to provide the
desired performance is affected by parameters other than temperature and frequency.
Namely the geometry, stiffness and the structure to which the control system is applied
will affect the performance.
The loss factor of a material is a dynamic property that can define damping
performance:
The following data are the results of 3M damping foil 2552 being tested per ASTM
E756-83. A sample was applied to a 8.0 inch by 0.5 inch by 0.06 inch steel beam.
The beam was tested over a temperature range of -40° to 140°F, in increments of
10°F. Beam modes 2 through 7 were monitored for system damping measurements.

Test Method: The following data were obtained by doing a frequency sweep from
1 to 100 radians/sec (0.16 to 16 Hz) at 5 different temperatures: -20°, 10°, 0°, 10°,
and 22°C. A 3 point bend geometry was used on the Rheometics RSA II. Time –
temperature superposition was used to create the master curve for a reference
temperature of 22°C.

T = 22°C
Data Interpolation:
To determine the damping properties at ambient temperature 72°F (22°C), proceed
as follows:
1) Locate the desired frequency on the bottom HORIZONTAL scale.
2) Follow the chosen frequency up to the point of intersection with the
plotted data.
3) From this intersect, go left to the vertical scale.
4) Read the COMPOSITE LOSS FACTOR for the chosen frequency.
Note:
Please note that the data has been determined by combining 3M™ Damping
Foil 2552 with a panel of 0.018" thick stainless steel with a hardness of T-22 and is
presented as a reference to the damping that can be achieved when combined with a
material of this description and tested at ambient temperature of 72°F (22°C).
Solvent and Fuel
Resistance
When properly laminated between two impervious materials, the polymer will
resist intermittent exposure to mild acids and alkalies, most oils, grease, gasoline,
kerosene, JP-4 fuel, hydraulic fluids, and other typical aromatic and aliphatic
hydrocarbon and ketone solvents.
Note:
Continuous submersion in chemical solutions like solvents or fuels is not
recommended.
