Solvay Zeniva Polymers: Replacing Metal in Implantable Devices

Screws used to fix joints after trauma are another important application, and artificial knees (pictured below) are a big future goal: "There are thousands of knee surgeries every year," says Jeff

PEEK Applications - From Automotive to Knee

Solvay entered this market about ten years ago
.
At that time, PEEK was already widely used in many other fields, such as automobiles, aircraft parts and 3D printing
.
It has also dabbled in the medical field, but it has been a long process to expand its application to implantable medical devices
.
"Entering the implant market is never easy," Jeff said
.
"We need to do biocompatibility testing and make sure the material meets regulatory requirements so we can provide all the information to the manufacturer to speed up the certification process
.
"

But in the end, the facts speak louder than words: PEEK is considered one of the most recognized materials for structural applications, including orthopedics, where strength, durability and biocompatibility are all critical
.
This is yet another example of the benefits of polymers in a range of medical applications, such as haemodialysis membranes and drug-protective blister wraps made from them
.

In order to make Zeniva® PEEK more suitable for medical implants, we are working to improve its fusion with the bone structure
.
"By partnering with a number of small companies focused on technologies that facilitate bone fusion, we're trying to help bone grow better on implants," explains Jeff
.
“To further serve humanity, it is critical to stay at the forefront of innovation
