Experimental research concerning the plastic materials behaviour in medical engineering

[EN] In literature, polymeric materials have a number of properties which are divided into three broad groups: 1. intrinsic properties arising from the chemical structure of the material, 2. technological properties resulting from processing methods and techniques used to obtain the piece or the finite product 3. properties arising from the use conditions of polymeric materials (products). In literature it is used the term of polymers property that summarizes the polymeric materials systemic properties assembly from the planning stage, to the finite product. Within the polymeric materials properties, the mechanical properties are analyzed extensively, especially in the case of the polymers used in medical applications. The paper presents, in a systemic form, the study of the tensile behaviour for a number a polymers used in the medical applications: Acrylonitrile butadiene styrene (ABS), Polycarbonates(PC), Polyamide(PA6), Polypropylene(PP),etc.
