VESTAKEEP® obtains medical test report from authorized organization

Evonik’s VESTAKEEP® i-Grade PEEK recently obtained the Biocompatibility Test Report from Zhejiang Institute for the Control of Medical Devices.

Zhejiang Institute for the Control of Medical Devices is the China Food and Drug Administration (CFDA) affiliated and qualified testing center. The comprehensive test of VESTAKEEP® i-Grade PEEK followed the GB 16886 standard series. PEEK has successfully passed all related tests in vivo or in vitro, which indicate that VESTAKEEP® i-Grade PEEK is of excellent biocompatibility. The report will help Evonik’s customers to get their product approved and Evonik to further explore the applications of the product in medical field.

Traditionally, metals were the materials of choice for spinal cages and other implants in the human body, but recently the high-performance plastic polyetheretherketone (PEEK) has proven a serious and even more desirable alternative. In addition to PEEK’s excellent biostability and biocompatibility, its x-ray transparency and elasticity are unreplaceable by metals. What’s more, the elasticity of PEEK closely corresponds to that of a bone. This allows an optimal transmission of force between the implant material and the natural bone, which can in turn have a positive effect on bone healing.

The application areas of PEEK have been extended from spinal implants, dental, skull implants, heart valve, to innovative areas such as gastrointestinal stent, implantable pump and hypoglossal nerve stimulation system.

According to Dominique Straessler, Head of High Temperature Polymers, High Performance Polymers Asia, “obtaining this report allows us to enter the market in China and beyond and give our customers a valuable alternative for their material of choice.”

Now, multiple Chinese manufacturers of spinal cages have already approached Evonik and used VESTAKEEP®i-Grade PEEK in their product development and clinical.
