摘要: Increasing environmental concern encourages the development of new ways to recycle medical products. Post-consumer products are suited for recycling because their life-span, but used have be disinfected before recycling. Therefore, influence different disinfection processes during on processibility and mechanical properties thermoplastics was investigated. As processes, steam with electron beam gamma radiation were selected. The characterisation recyclates undertaken PE PP from syringes. melt mass-flow rate (MFR), dynamic properties, tensile fracture mechanics parameters examined. A comparison results showed that stiffness strength remain nearly constant, deformation behaviour tends influenced. selection appropriate can avoid unnecessary alteration properties. Thus, as well up a dose about 25 kGy decontaminating
