Chemical and Physical Properties

Free Resources

  • NIST Data Gateway: Links to selected online NIST databases (both free and those available for purchase). .

  • NIST Chemistry WebBook: provides access to thermochemical, thermophysical and spectral data for selected chemical substances.

  • Chemspider: provides data on physical, thermodynamic, and spectra data.

  • MatWeb: Data sheets of thermoplastic and thermoset polymers such as ABS, nylon, polycarbonate and others; metals such as aluminum, cobalt, copper and others; ceramics; plus semiconductors, fibers, and other engineering materials.

  • Smithsonian Physical Tables.

  • Physical Properties Sources Index (PPSI): A comprehensive index of physico-chemical and other material properties in both web and print resources. Swiss Federal Institute of Technology Zurich.

  • PolyInfo:  Polymer properties, structures, names, processing, and methods. ~100 types of properties including thermal, electrical and mechanical are range searchable.

  • WolframAlpha: Provides "dynamic computations based on a vast collection of built-in data, algorithms, and methods." Information on solution chemistry.

  • Thermolit: "NIST Literature Report Builder for Thermophysical and Thermochemical Property Measurements". Thermolit gives you the conditions for the measurement and the full literature reference, but NOT the actual property value.
