Different formulations with PVC and TPU matrices were prepared with the addition of plasticizers at different content (wt%), within plausible ranges for an application context (from 15 wt%). According to the literature, plasticizers contents between 15 and 50 wt% are recommended for PVC plasticization . Moreover, the concentrations chosen are well beyond a potential antiplasticization range commonly found at low concentrations for most plasticizers especially in PVC . The formulations are presented in Table . To achieve this, 15 g of PVC are added to 150 ml THF at 50 °C and stirred until completely dissolved.
