Polymer resin matches bone

Polymer resins manufactured by Victrex Peek are already used in a wide variety of medical applications, including reusable surgical and endoscopic instruments, electromedical devices and assorted probes and pumps.

Now, the latest addition to the company’s family of polaryletherketone resins is set to become one of the first thermoplastics to be used in long-term in vivo applications like hip, spinal and dental implants.

Peek Optima LT combines the characteristics of its predecessors – purity, sound mechanical properties, fatigue resistance, and resistance to chemicals and hydrolysis – with biocompatibility. The polymer can be tailored to match the stiffness and performance of human bone, and has an inherent lubricity which could make it useful in artificial joint applications.
