5.6. Renewable Polyurethanes

Renewable thermoplastic and thermosetting polyurethanes generally include biopolyols and synthetic isocyanates but renewable isocyanates are emerging.

5.6.1. Natural Oil Polyols

NOPs or biopolyols are derived from diverse vegetable oils by several different techniques, which lead to various properties. Most NOPs are based on natural castor oil, soybean oil, and linseed oil.
For example, without claiming to be exhaustive:
• Ford Motor Company uses soy oil in the seats, headrests, armrests, soundproofing of several car models
• The Dow Chemical Company proposes its RENUVA™ technology used to produce biobased polyols with high renewable content in the finished product and performance similar to petroleum-based polyols.
• Alberdingk ...
