dc.description.abstract | As a consequence of the high production and simultaneous consumption of polyurethanes
(PU) a great volume of PU waste is landfilled. In this scenario, suitable and efficient routes for PU
waste recycling have been searched for many years. In this work two series of PUs using different
recycled PU sources were synthesized: a thermoplastic PU series using a glycolysated polyol
obtained from the glycolysis of elastomeric PU waste (chemical recycling) and a PU flexible foam
series loaded with PU dust waste created in the shaping of PU surf tables (mechanical recycling).
Results showed that the incorporation of recycled components in the formulation improved
mechanical properties both in the case of thermoplastic polyurethanes and polyurethane foams. The
optimum glycolysated polyol was fixed in 15% over the total polyol weight for thermoplastic PUs.
In the case of foams, a maximum of 20% PU dust over the polyol weight was incorporated. | es_ES |
