Abstract

Poly ( ethylene terephthalate ) , known by the acronym PET and commercially as DACRONÂ , is chemically classified as a thermoplastic polyester polymer . This material has been widely used in the textile industry , in the production of plastic bottles and in health , with applications in medicine , where it is used for vascular grafts and cardiovascular prostheses . Besides biocompatibility , this material exhibits high strength , gloss and transparency , which makes this the preferred thermoplastic many sectors . In view of the good mechanical and biological materials reported in the literature that performance , the objective of this study is to evaluate the properties of PET and polyethylene by means of four tests : scanning electron microscopic, roughness , compressive strength , hardness , and comparing the PET performance against polyethylene material already used in the manufacture of prosthetic components . To do so , shall be made 120 specimens for each material , 30 for each proposed test , the dimensions and shapes determined by the rules of each test . To obtain the results of the statistical processing will receive data in order to make the correlation between the properties of PET and polyethylene.
