**2.2 Tensile measurement**

The first group of ASTM tensile bars with no preconditioning were tested in a universal tensile testing machine with a tensile pull rate of 2 mm/min. 5 samples of virgin PC, 50% PCR and 75% PCR, all with white resin and melt flow rate (MFR) of 10 g/10 mins. Next 50% PCR tensile bars (black) with MFR of 10 and 15 were tested. **Figure 1** shows a schematic of a tensile bar and a set-up image of the tensile test. From the load–displacement curves, yield or necking point, the EAB (elongation at break) and UTS (ultimate tensile strength) were recorded.
