Sterilizing medical devices with ethylene oxide (EO) is a common practice primarily due to its extensive material compatibility. Tyvek® retains its dimensional stability and integrity with no discoloration when steam sterilized under the controlled conditions mentioned above. This is because HDPE is radiation stable. Unlike medical-grade papers and films, DuPont™ Tyvek® offers sterilization compatibility with all of the most commonly used methods for sterilizing medical devices. 150 111
EO sterilization is typically a three-step process, starting with preconditioning in a room or cell, then sterilization in a chamber, and finally, desorption of gas in heated aeration in a room or cell. 0000475618 00000 n

EO packaging. The chart in Figure 1 classifies the polymers by absorption and desorption characteristics. The chemical compatibility data can be presented in one of two ways. If residue issues are currently a problem or may present a challenge to a new device, consult with a sterilization provider to discuss minimizing the effects of the ethylene oxide sterilization process. 0000466256 00000 n
For many materials used to manufacture medical device and pharmaceutical components and packaging, it is possible to select and validate an appropriate and compatible industrial sterilization technique. The degree and types of changes to a particular plastic depend on the nature of the polymer, whether or not it has had stabilizers added to it during manufacture, the intensity of the radiation used and how long the parts are irradiated. 0000047330 00000 n
Added heat – heat aids in the off-gassing process so it is helpful to keep as much heat in the chamber as possible after the sterilization process. The TCL is a calculated value that takes into consideration the surface area of a device and the EO and ECH residue levels in order to determine if irritation will be an issue. 0000046908 00000 n
