Abstract

This presentation will covers both grade selection and processing of implantable PEEK materials.

Numerous physcial, mechanical, and processing requirements, as well as application driven properties must be considered in seleting the proper grade of PEEK. This portion of the presentation identifies these considerations in order to guide those specifying materials to an informative material decision.

The second part of the presentation provides an overview of key PEEK processing considerations that will help guide those producing implantable PEEK components around common pitfalls, and will aide in successful manufacturing.
