Cryogenic Machining of PEEK

To date, despite the important role temperature plays in the machining of thermoplastic polymers, precise control of heat removal from the machining operation has not been possible since coolants traditionally used in machining metal parts are: (1) not suitable for medical polymers, and (2) do not offer temperature control capability for optimized performance. Therefore, the following objectives are critical in designing an effective, economical cooling system for machining thermoplastic polymers: (i) provide a reisdue-free coolant, (ii) provide fast startup and cooldown, (iii) prevent overcooling/ undercooling and (iv) allow machining of various polymers with different glass transition temperatures.



Particulate and Gravimetric Wear Rate Analysis and Flexural Fatigue Testing of a PEEK Medial Knee Interpositional Arthroplasty Implant

This study is a summary of the PEEK Mobility wear particulate, grvimetric wear rate, and flexural fatigue testing used in preparation for the CE Mark Technical File submission for the PEEK Mobility implant.

PEEK-Optima HA Enhanced Biomaterial: Pre-Clinical in vivo and in-vitro Characterization

  This presentation reviews current in-vivo and in-vitro studies of Hydroxyapatite-enhanced PEEK.



Macromolecular and Morphological Characterization of Medical Grade PEEK Polymers

In this study, we examined the morphology of four medical grade PEEK polymers using a variety of characterization techniques to determine whether there were significant differences between their molecular and nanostructures.
