Created in 1978 under the auspices of the American Institute of Chemical Engineers the Design Institute for Physical Properties (DIPPR) has become the premier research collaboration on physical property data to satisfy process engineering needs.

DIPPR focuses on (a) culling all available data from worldwide citations, (b) recommending data values based on an extensive GOLD STANDARD evaluation methodology, (c) measuring values if data is not available or considered of poor quality and, (d) providing estimated values using proprietary methods for those cases where experimental data is not available.

DIPPR sponsors leverage scarce research funds and personnel time through the research collaboration and, in addition, research funds are augmented through income derived from licensing a non-proprietary version of the database.
