Development of Polyurethane with Superior Curability Prepared by Polyisocyanate using Novel Biomass-based Diisocyanate

Abstract

We have developed and commercialized novel biomass-based diisocyanate 1,5-pentamthylenediisocyanate, STABiO^TM PDI^TM (PDI) and the polyisocyanate hardener under the concept of high performance and sustainable isocyanate. PDI and its polyisocyanate hardener prepared from biomass resource show high curability with alcohol to produce high performance polyurethane compared to petrochemical 1,6-hexamethylenediisocyanate (HDI), and the polyisocyanate hardener based polyurethane. This paper describes the properties of PDI, the polyisocyanate hardener and polyurethanes.
