The goal of this study was to provide both the members of the Plastics Division of the American Chemistry Council (ACC) and the general public with the most up to date LCI data for the resins and polyurethanes precursors analyzed in this database. The database will also be publicly available at the U.S. LCI Database website (http://www.nrel.gov/lci/). The results of this analysis are presented in both English and Metric units for the benefit of the eventual intended audience, which may include international users.
