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.
3M? Damping Foil 2552 on 18 mil Stainless Steel
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).
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.
