Medical quality radiation resistant plasticized poly(vinyl chloride) (in English)

Polimery 2003, No 6, 434


Summary

The effect of modification of plasticizer and stabilizer systems on the radiation resistance of flexible PVC compositions for medical applications was studied. Samples were irradiated in a linear accelerator LAE 13/9 of electrons beam with dose of 25 kGy. Biological-chemical and mechanical-physical property data were measured for irradiated and additionally ageing plasticized PVC compositions of modified formulations and compared with those of standard medical grade compositions. Post-irradiated stability of flexible PVC meeting the Pharmacopoeia requirements has been achieved.


Keywords: plasticized PVC, medical materials radiation sterilization, radiation resistance, costabilizers, chemical and biological properties
