DIPPR

Design Institute for Physical Properties

The Design Institute for Physical Properties (DIPPR) is the world's best source of critically evaluated thermo-physical and environmental property data. Using a proprietary data evaluation methodology DIPPR’s recommended values allow practitioners to quickly produce results from their computational tools rather than spending time ensuring that the underlying data are robust. DIPPR data are used by leading chemical, petroleum, and pharmaceutical companies throughout the world and used extensively in third-party software.
