Effects of thermal sterilization and disinfection on the properties of polymers
- 52 Downloads
1. Thermal sterilization of medical components made of polymers results in irreversible thermal oxidation as a result of the combined action of the high temperatures and the sterilization medium; this can lead to deterioration in the functionally important physicomechanical characteristics.
2. The deterioration is influenced considerably by the chemical nature of the polymer and that of the sterilization medium, as well as by the temperatures and times employed.
3. The choice of method in thermal sterilization should be determined mainly by the nature of the polymer.
