434 • 435 • 436 Technical Data November, 2013 Product Description 3M™ Vibration Damping Tapes are low temperature 3M™ Viscoelastic Damping Polymers coated on a dead soft aluminum foil constraining layer. They have pressure sensitive properties and are furnished in roll form and designed for direct, pressure sensitive application to metal and composite panels for vibration damping purposes. The combination of the low temperature 3M viscoelastic polymers and an aluminum constraining layer has proven to be an unique construction with exceptional ability to damp resonant vibrations in the temperature range of -76° to Product Construction Product Liner Aluminum Damping Polymer 3M™ Vibration Damping Tape 434 Polyethylene (Blue) 5.5 mils (0.14 mm) (Dead Soft Aluminum Foil) 2.0 mils (0.05 mm) Synthetic 3M™ Vibration Damping Tape 435 Polyethylene (Blue) 8.0 mils (0.20 mm) (Dead Soft Aluminum Foil) 5.5 mils (0.14 mm) Synthetic 3M™ Vibration Damping Tape 436 Polyethylene (Blue) 12.0 mils (0.30 mm) (Dead Soft Aluminum Foil) 5.5 mils (0.14 mm) Synthetic 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.

3M™ Vibration Damping Tapes 434 • 435 • 436 Typical Dynamic Damping Properties Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. Dynamic Mechanical Properties of 3M™ Viscoelastic Damping Polymer Type 830 (Without Foil) Note Regarding Dynamic Mechanical Properties: The shear storage modulus (G') and loss factor of a viscoelastic adhesive are two parameters used to partially define the damping performance when used in the form of a constrained layer damping treatment. The above curves illustrate these data as a function of frequency and temperature in the form of a reduced temperature nomograph. While the damping performance of a constrained layer damping treatment depends largely on the dynamic mechanical properties of the viscoelastic adhesive alone, it is also dependent on other parameters. Namely the geometry, stiffness, mass and mode shape of the combination of the damper and the structure to which it is applied will also affect the damping performance. To determine the dynamic mechanical properties at the desired temperature and frequency proceed as follows: 1. Locate the desired frequency on the right vertical scale. 2. Follow the chosen frequency horizontally to the desired temperature isotherm. 3. From the intersect, move vertically up and/or down until crossing both the modulus and loss factor curves. 4. Read the shear storage modulus and loss factor values from the left vertical scale. Features • Pressure sensitive construction for easy application.

  • Excellent aging qualities of the 3M viscoelastic damping polymer type 830 provide long term performance and has excellent resistance to most hydrocarbon and/or aircraft type solvents.
  • Wide temperature range for damping. Usable from -76° to 68°F (-60° to 120°C) at 100 Hz plus higher temperatures at higher frequencies.
  • These linered products offer the user die-cut capability. - 2 -
