Continuous Production of Water-Borne Polyurethanes: A Review

open access: yesPolymers, 2020
Water-borne polyurethanes are novel functional polymers that use water as the dispersion medium. When compared with solvent-borne polyurethanes, water-borne polyurethanes are more environmentally friendly and easier to transport and store.
