Purpose: This paper presents results of studies on the effect of the sterilization process and aging process (for comparison) on the mechanical properties and the surface quality of low density polyethylene PE-LD used in biomedical applications. Design/methodology/approach: In order to determine the changes in the surface structure of polyethylene PE-LD measurement of angle and roughness of samples were made. There were also measured mechanical properties - Shore hardness and tensile strength of PE-LD samples. Findings: Results of this study indicate that the sterilization process and the aging process does not significantly affect the mechanical properties of polyethylene. These processes influence the structure of its surface, which is very important due to the its use in medical. Practical implications: Low density polyethylene PE-LD is used in the manufacturing of laboratory equipment, such as syringes, gloves, laboratory dishes, catheters used in hemodialysis, connectors for the surgical drains, the surgical drains used in the treatment of sinuses, tracheostomy tubes. Originality/value: Results are the base for further investigations of biomedical materials. Research are essential to search for new biomedical applications for polyethylene.
