“…Recycled poly(ethylene terephthalate) (rPET) was produced by Eco Selekta Italia Srl (Salorno, Italy) from bottles used for beverages (density ISO 1183(A): 1.328 g/cm 3 ; MVR ISO 1133 = 115 ml/10 min; intrinsic viscosity ISO 1628-5 = 0.70 dl/g). A commercial nucleating agent (Procaster by Polichem) was used (3.5 wt% related to rPET) in order to obtain fully crystallized rPET matrix under the selected moulding conditions.…”

“…PET resins are historically classified by their intrinsic viscosity [η] and are selected based on the manufacturing process requirements and the end-use application. For BO-PET, [η] values between 0.6 and 0.7 dL/g are common [ 2 ]. At relevant processing temperatures, the shear viscosity curves of such resins show a pronounced Newtonian plateau and a relatively low zero shear viscosity η 0 compared to other polymers (e.g., [ 3 , 4 , 5 ]).…”

“…One the other hand, these special molecular characteristics lead to a low melt strength which is of disadvantage for other processes, like blow molding or film blowing. To overcome this deficiency high Mw resins ([η] = 0.7–0.85 dL/g [ 2 ]) are typically used for PET bottles manufactured by blow molding. Furthermore, special machine equipment can be used in the case of blown PET films [ 6 ].…”

Film blowing of Poly(ethylene terephthalate) (PET) is challenging due its inherently low melt viscosity and poor melt strength. In this study, it is shown how the rheological properties of a commercial PET can be altered by reactive extrusion using either pyromellitic dianhydride (PMDA) or a multifunctional epoxy (Joncryl® ADR 4368) as chain extender, in order to improve the processing behavior during film blowing. The modified materials were characterized by shear and elongation rheometry and relevant processing characteristics, like melt pressure, bubble stability, and film thickness uniformity, were used to assess the influence of the type of modifier on processing and product performance. It is shown that PMDA is useful to increase the melt strength which leads to an improved bubble stability, while epoxy modified PET shows a reduced drawability that can cause problems at high take-up ratios. On the other hand, the epoxy modifier indicates a pronounced strain hardening during elongational deformation, and therefore leads to a better film thickness uniformity compared to the neat PET and the PET modified with PMDA. The differences with respect to processing performance are discussed and ascribed to the molecular structure of the materials.

“…Polyethylene terephthalate (PET) is thermoplastic polymer widely used in application as diverse as textile fibers, films, bottles and other moulded products [6]. One of the main reasons for the widespread use of PET is their possibility of producing a number of different grades over a broad range of molecular weights in a single multiproduct polymerization plant [7].…”

This study suggests using the recycled plastic waste to prepare the polymer matrix composite (PMCs) to use in different applications. Composite materials were prepared by mixing the polyester resin (UP) with plastic waste, two types of plastic waste were used in this work included polyethylene-terephthalate (PET) and Polyvinyl chloride (PVC) with varies weight fractions (0, 5, 10, 15, 20 and 25 %) added as a filler in flakes form. Charpy impact test was performed on the prepared samples to calculate the values of impact strength (I.S). Flexural and hardness tests were carried out to calculate the values of flexural strength and hardness. Acoustic insulation and optical microscope tests were carried out. In general, it is found that UP/PVC composite exhibit the optimum values compared to UP/PET composite in all properties under test. From the experimental results, it can be concluded that the prepared composites from the waste could be utilized as precast or partitions inside the buildings with improved mechanical properties
