Experimental Materials Three different polymers were employed: a recycled poly(ethylene terephthalate) with a MFI value of 94 dg/min from beverage bottles (in flakes), a poly(butylene terephthalate) with a MFI value of 62 dg/min, and a commercial polypropylene (PP) (MFI value of 7.0 dg/min).
All the materials were also previously vacuum-dried at 80 °C for 48 hours.
All the materials displayed a brittle behavior.
