| Summary: | The physicochemical properties of polyethylene terephthalate in amorphous state, obtained from industrial surpluses, for the manufacture of non-returnable bottles were characterized. From the above, an intrinsic viscosity of 0.538 +/- 0.024 dL / g, acetaldehyde concentration of 4.00 +/- 2.00 ppm, density of 1.53 +/- 0.05 g / cm3 and melt index of 129 +/-22 g/10min was defined for pelleting. Second, the physicochemical and mechanical properties of preforms and non-returnable 2L bottles, manufactured with the current dosage of 3% PET in amorphous state, were determined. It was obtained 0.830 +/- 0.015 dL / g of intrinsic viscosity, 2.32 +/- 0.605 ppm of acetaldehyde concentration, resistance to vertical compression of 29.98 +/- 1.72 kg-F and, without failure of any bottle in the test of internal pressure resistance at 135 psi for 13 seconds. |
