ALPHARETTA, Ga. -- Solvay announced at the recent AAOS 2017 that it has introduced two new lubricated grades of Zeniva® polyetheretherketone (PEEK) to its portfolio of biocompatible polymers for use in implantable devices.

Biocompatible Lubricated PEEK

New Zeniva® ZA-500L and ZA-600L PEEK each offer melt indexes specifically tailored for injection molding, enabling broader design latitudes for customers developing next-generation implantable devices.

Dane Waund, global marketing manager for Healthcare at Solvay’s Specialty Polymers business unit, said:
“Zeniva® PEEK continues to drive innovation in long-term implantable devices, including more complex and integrated designs. With the introduction of these two lubricated grades of Zeniva® PEEK, our customers can better leverage the benefits of injection molding over conventional machining processes, and introduce differentiated and higher-performing new concepts more quickly to the fast-growing implantable device market.”

Benefits Over Metals

  • Solvay’s implantable Zeniva® PEEK is well-recognized for the numerous benefits it offers vs. implantable metals. 
  • Its modulus of elasticity is similar to that of cortical bone, minimizing reduction in bone density by maintaining normal stress on surrounding bone tissue. 
  • It also eliminates the risk of allergic reactions to heavy metals, and its radiolucent properties will not interfere with X-ray and computed tomography scanning procedures.

Jim Hicks, Technical Development Engineer for Healthcare at Solvay’s Specialty Polymers global business unit, said:
“The orthopedic industry has challenged its supply partners to deliver biocompatible polymers that enable more innovative implantable device designs. These new additions to our Zeniva® PEEK portfolio offer new possibilities for designing and molding unique, new implants that incorporate smaller, thinner and lighter components, and to deliver them consistently within a validated medical production process compatible with long term implant applications.”

Zeniva® PEEK

Zeniva® PEEK is part of Solvay’s Solviva® family of biomaterials, which also includes three other distinct polymer chemistries to offer a broad and growing range of options for implantable devices used in orthopedics, cardiovascular, spine and other applications.
  • In addition to Zeniva® PEEK, the portfolio includes Proniva® self-reinforced polyphenylene, Veriva® polyphenylsulfone and Eviva® polysulfone. All Solviva® Biomaterials can be sterilized using conventional methods, such as gamma radiation, ethylene oxide and steam. 
  • They demonstrate no evidence of cytotoxicity, sensitization, intracutaneous reactivity or acute systemic toxicity, based on biocompatibility testing as defined by ISO 10993:1. 
  • These sterilizable products are available in grades for injection molding or extrusion, as well as stock shapes for machined components.
