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 ...

Focusing on eco-friendly materials, cellulose nanocrystals (CNC) have gained attention as nanoreinforcement due to their exceptional properties conferred by the elevated length/diameter aspect ratio and high specific ...

Since polyol is one of the major components in polyurethane foam synthesis, introducing renewably sourced polyols in the foam formulation leads to materials with high renewable carbon content. A series of flexible ...

Precursors have been satisfactorily synthesized from lignocellulosic biomass for later use in the synthesis of polyurethanes resulting in competitive final properties with those of petroleum derived polyurethanes

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 ...

Se prepararon nanocompuestos de espuma de poliuretano conductores mediante la incorporación de flakes de grafeno. Los flakes de grafeno se obtuvieron a partir de grafito por el método de exfoliación líquida en N metilpirrolidona ...

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. ...

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, ...
