Biobased Pentamethylene Diisocyanate (PDI)


A new building block for polyurethane chemistry

• The first isocyanate with significant biocontent: 71% renewable carbon*

• Produced very efficiently from biomass combining biotechnological and chemical processes, e.g. energy efficient gas phase technology

• First diisocyanate in 30 years to be fully developed and scaled-up

• The corresponding derivatives are similar to hexamethylene diisocyanate (HDI) based ones, yet offer some advantages

High performance enabled by nature * Confirmed by radiocarbon method 14C measurement according to ASTM-D6866 standard

High performance enabled by nature


The first biobased polyurethane crosslinker

• DESMODUR® eco N 7300: first PDI derivative launched April 2015 at the European Coatings Show

• Full REACH registration to be completed in 2016

• Development of technology platform based on PDI

• Innovation multi-awarded:
