By integrating the osteoconductive properties of calcium-phosphate based additives into its market-leading RESOMER® portfolio of bioresorbable polymers, Evonik can further support medical device customers worldwide to enhance the performance of orthopaedic applications used to heal or grow bones.
RESOMER® Composites feature precise degradation rate profiles and mechanical properties such as elastic modulus that can be tailored to match the natural bone. Such benefits can help to minimize stress shielding for bone fixation devices such as interference screws, suture anchors and fracture plates to encourage faster patient healing.
A range of standard and customizable product grades with calcium-phosphate material options including Hydroxyapatite (HA), beta-tricalcium phosphate (β-TCP) and Bicalcium phosphate (BCP) will be available under the RESOMER® Composite line. The first composite product to be launched by Evonik is
RESOMER® Composite L 210 S plus 25% HA. Additional standard grades with β-TCP additives are scheduled to be introduced later this year.
RESOMER® Composites are supplied to customers as ready-to-use pellets that are easy to process for a uniform additive distribution. They are also radiolucent to avoid potential interference with X-ray equipment.
Dr. Andreas Karau, Global Head of Biomaterials for Evonik, said: “Our new line of composites combine the osteoconductive benefits of calcium-based phosphates with a 30 year track record of RESOMER® polymers for functionality, biocompatibility, safety and supply security.”
“With elastic modulus properties and tailored degradation profiles that match the natural bone, we look forward to supporting medical device customers to enhance the performance of their bioresorbable implants.”
Medical device companies who are attending the Medtec Europe trade show in Stuttgart, Germany from April 17 to 19 are encouraged to visit Evonik at booth 9C28.
