What are the effects of sterilization on the mechanical properties of silicone rubbers?
In the medical and biopharmaceutical fields, millions of silicone rubber-based tools and devices must be sterilized on a daily basis. During the sterilization process, silicone components are commonly exposed to various types of treatments, including single or multiple doses of radiation. While these processes are essential for sanitizing rubber parts, they often have an adverse effect on the integrity of the material. In this study, we evaluate the mechanical properties of three types of commercially available silicone rubbers:
- platinum cured liquid silicone rubber - LSR
- platinum cured high consistency rubber - HCR
- peroxide cured high consistency rubber - HCR
