How we scored it

Polymer of caprolactone, trimethylolpropane and HDI cyclic trimer -- all conventionally petrochemical monomers; no natural fragment identified.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.

Where it comes from

Manufactured entirely from petrochemical lactone, polyol and diisocyanate-trimer monomers. No bio-based route is used for this grade.

In plain English

A fully synthetic film-forming polymer built from petrochemical building blocks, including a caprolactone- and diisocyanate-based resin.

CosIng definition: Polyurethane-45 is a polymer made by the reaction of epsilon caprolactone and Trimethylolpropane with the cyclic trimer of hexamethylene diisocyanate.
