In the case of medical technology products that are to be used several times, it is absolutely necessary to sterilize them after each use. That is why, only materials that withstand the stresses of the sterilization process can be used for such products. Components made of a hard (shaping) and soft (sealing) component are usually required. These are often made from a combination of PEEK and silicone as these meet the requirements. Due to the developments in materials technology, more and more plastics are available that also fulfill these requirements.

The aim of the thesis is to research the currently available materials with which 2 component plastic parts can be produced for multiple sterilization. In order to replace existing products that were previously made of PEEK & silicone. So that the manufacture of these products can be made easier and more efficient.
