Damping Foil 2552 Technical Data January, 2012 Product Description 3MTM 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 140F (0 to 60C), with survivability from -25 to 175F (-32 to 80C). 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 140F, in increments of 10F. Beam modes 2 through 7 were monitored for system damping measurements. 3MTM Damping Foil 2552 3MTM Damping Foil 2552 Typical Damping Properties (continued) 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 22C. 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 22C. 3MTM Damping Foil 2552 on 18 mil Stainless Steel T = 22C Data Interpolation: To determine the damping properties at ambient temperature 72F (22C), 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 3MTM 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 72F (22C). 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. -2- 3MTM Damping Foil 2552 Product Construction and Typical Physical Properties Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.
