Nomograph

The 3M ultra-pure viscoelastic damping polymer 242 damping properties are shown in the “reduced temperature format” nomograph. The nomograph shows the Viscoelastic Damping Polymer’s Loss Factor and Storage Modulus for various frequencies and temperatures in a single graph. The Shear Storage Modulus and Loss Factor are intensive properties of the Viscoelastic Damping Polymer alone.

The Loss Factor and Storage Modulus are the key measurement parameters and determine the level of potential damping capability that exists in the 3M viscoelastic damping polymer 242 at a specific temperature and frequency.

The Loss Factor and Storage Modulus for the 3M viscoelastic damping polymer 242 is found by selecting the frequency desired of an application and extending a horizontal line from that frequency until the desired application temperature isotherm is intersected. Extend a vertical line from this first intersection point of the desired frequency and temperature isotherm so that it intersects the Loss Factor and Storage Modulus curves. The Loss Factor and Storage Modulus values are found on the left hand scale by extending a line horizontally from these second intersection points on the Loss Factor and Storage Modulus performance cures.
