- Properties
EXCEPTIONAL WEAR PROPERTIES IN ARTICULATING DEVICES
CFR PEEK-OPTIMA demonstrates excellent wear performance against ceramic, metal and polymeric counterfaces. This wear is significantly lower than that observed for UHMWPE/COCrMo wear couples under identical conditions. In addition to reduced wear, this material may offe increased implant life span and avoidance of metallic wear debris. Additionally, the improved mechanical properties compared to UHMWPE may allow thinner parts, lower weight prostheses and a greater design flexibility. Hip simulator testing against ceramic counterfaces confirms that significantly less wear is produced with CFR PEEK-OPTIMA compared to UHMWPE. Furthermore, CFR PEEK-OPTIMA wear debris showed significantly less cytotoxicity compared to metal wear debris in vitro.
EXCEPTIONAL FIBER-MATRIX BOND STRENGTH
CFR PEEK-OPTIMA provides an excellent fiber-to-matrix interfacial bond strength. The interfacial strength between carbon and PEEK is at least an order of magnitude stronger than that between carbon fibers and UHMWPE. Additionally, the PEEK-OPTIMA polymer matrix offers superior creep performance compared with UHMWPE.TAILORED MECHANICAL PROPERTIES
The compounding of PEEK-OPTIMA polymer with short carbon fibers significantly increases the strength of the natural unfilled polymer to address the needs of applications requiring a higher stress tolerance. Especially important for orthopedic applications, the flexural stiffness of CFR PEEK-OPTIMA is similar to cortical bone, thus reducing complications
associated with stress shielding.
PROVEN BIOCOMPATIBILITY
Extensive testing of CFR PEEK-OPTIMA compound to ISO 10993 standards demonstrated no evidence of cytotoxicity, systemic toxicity, irritation or any macroscopic reaction response. Results have been lodged with the US FDA and can reduce the time and expense of the approval process.
PROCESSING AND DESIGN FLEXIBILITY
CER PEEK-OPTIMA compound is available in granular form for injection molding and extrusion. Established techniques can be used for improving fixation via hydroxyapatite and titanium coatings.
