Instructions: This page allows you to quickly access all of the polymers/plastics, metals, ceramics, fluids, and other engineering materials in the MatWeb material property database.  Just select the material category you would like to find from the tree. Click on the [+] icon to open subcategory branches in the tree. Then click the 'Find' button next to its box.  You can then follow the links to the most complete data sheets on the Web, with information on over 1000 available properties, including dielectric constant, Poisson's ratio, glass transition temperature, dissipation factor, and Vicat softening point.
