Design and Routes for Sustainable Polyurethanes

Symposium Organizers: Dr. Sylvain Caillol, Institute Charles Gerhardt, University of Montpellier; Prof. Henri Cramail, Laboratoire de Chimie des Polymères Organiques, University of Bordeaux

Polyurethanes rank 6th among all polymers with a global production of 18Mt in 2015. The business of polyurethanes is a $71.9 billion enterprise and a key element of the U.S. economy. The industry directly employs more than 235,200 Americans and operates in more than 1,000 locations across the United States. Polyurethanes are highly versatile materials capable of solving many problems and are used in the construction, furniture, bedding, automotive, binder and many other industries. They are used as insulators, adhesives, sealants and binders in a variety of construction products and in numerous other uses. The desire and need for more sustainability and more energy efficient materials has encouraged the use of more bio-based chemicals. Hence, lots of bio-based polyols are developed from vegetable oils or sugar derivatives to yield bio-based polyurethane products. However, to prepare these polyurethanes, isocyanates are still required. The issue with isocyanates is mainly due to their toxicity. Therefore various routes for the synthesis of isocyanate-free polyurethanes have recently gained increasing attention from both scientific and industrial communities. These non-isocyanate polyurethanes (NIPUs) are really promising polymers that could be used in various application sectors. We propose in this symposium “DESIGN AND ROUTES FOR SUSTAINABLE POLYURETHANES” to gather the most high-level contributions from academic and industrial community on the remaining challenges for sustainable PUs and NIPUs.

The objective is to address issues and gaps concerning:

  • Innovative and promising bio-based monomers for industrial PUs and NIPUs
  • Monomer reactivity and molar mass issues for non-isocyanate PUs
  • Access to NIPU foams
  • Water borne NIPUs
  • Life cycle assessment on PUs and NIPUs
  • NIPUs up-scaling
  • Characterizations, derivatizations and promising applications for NIPUs
