Question: What is the shelf life of uncured medical silicone?
Answer: The typical shelf life of uncured medical silicone may range from 6 to 24 months; it is normally labeled with a “best use before” date. If the medical silicone has passed the recommended date, it still can be mixed, molded, and used. However, the properties of the medical silicone are likely to be affected. Therefore, the medical silicone parts must be thoroughly inspected and tested to insure that all the necessary requirements are met before using them.
