Sterilization and Biocompatibility Q&A
-
Do you have any experience dealing with how or whether silicone shrinks when it is sterilized before use? I am interested in this to be able to understand the fit of some silicone parts into polypropylene parts (which I know do shrink during sterilization). Do you know the percentage shrink? It is possible that the product I am designing will be sterilized using various means such as boiling, microwaving, or autoclaving.Answered July 13th, 2011 by Expert:My experience is that silicone does very well dimensionally with respect to most forms of sterilization. I have never seen a percentage shrink published, however. Usually, what is required is that the company perform feasibility studies using the different forms of sterilization followed by dimensional analysis. We can assist with applying the sterilization methods, if needed.
