Properties of flexible polyurethane foams with isocyanate functionalized lignin
(Elsevier, 2017-02-20)
A commercial kraft lignin (k-lignin) was successfully functionalized by means of the reaction of an isocyanate group from isophorone diisocyanate (IPDI) with hydroxyl groups present in lignin (k-IPDI), for their further ...
Thermoplastic polyurethanes with glycolysate intermediates from polyurethane waste recycling.
(Elsevier, 2017-10)
The polyol is a major component in polyurethane formulations and therefore introducing to the formulation recycled polyol (obtained during decomposition process) allows decreasing the usage of pure petrochemical components. ...
Two different incorporation routes of cellulose nanocrystals in waterborne polyurethane nanocomposites
(Elsevier, 2016-03)
The renewability, availability and low-cost of eco-friendly cellulose nanocrystals (CNC), have gaining attention for nanocomposites preparation due to their unique properties in the nanoscale and their water dispersibility, ...

(Elsevier, 2017-02-20)
A commercial kraft lignin (k-lignin) was successfully functionalized by means of the reaction of an isocyanate group from isophorone diisocyanate (IPDI) with hydroxyl groups present in lignin (k-IPDI), for their further ...
Advanced and traditional processing of thermoplastic polyurethane waste
(Elsevier, 2022-04)
In this work different ways to valorise discarded ear tags made of TPU from livestock sector were studied. This singular residue does not require separation from other plastics like other industrial and urbane wastes, which ...
