AKA: Aliphatic urethane polymer, HDI-PPG copolymer
Synthetic
Clean
OriginSynthesized from hexamethylene diisocyanate (HDI), polypropylene glycol (PPG), and polycaprolactone polyol starting materials. Produced through step-growth polymerization combining the isocyanate and polyol components via urethane linkage formation.
2-Oxepanone, Polymer with 1,6-Diisocyanatohexane, 2-Ethyl-2-(Hydroxymethyl)-1,3-Propanediol and a-Hydro-w-Hydroxy[Poly[Oxy(Methyl-1,2-Ethanediyl)]] Ether with D-Glucitol
