Healthcare

KetaSpire® PEEK and AvaSpire® PAEK are part of Solvay’s broad portfolio of high-performance healthcare plastics, which includes Radel® PPSU (polyphenylsulfone) and Udel® PSU (polysulfone). Both products are used in limited exposure applications required to withstand repeated exposure to sterilization as well as hospital cleaners and disinfectants.

  • Instruments
  • Sterilization cases and trays
  • Operating room equipment
  • Reusable medical devices


Solvay also offers Solviva® Biomaterials for use in implantable medical devices for short-term and long-term exposure. Based on biocompatibility testing as defined by ISO 10993:1, all of our healthcare products demonstrate no evidence of cytotoxicity, sensitization, intracutaneous reactivity or acute systemic toxicity.

Sterilization

Solvay's healthcare plastics can be sterilized using all commercial sterilization techniques, including steam, ethylene oxide gas, vaporized hydrogen peroxide and high-energy gamma radiation.

Since each application has unique performance and design criteria, it’s important to evaluate a material under conditions that best simulate the function of the component or system in its intended use. This includes cleaning and disinfection followed by sterilization in order to assess their cumulative effect on the material.

Cleaning & Disinfection

KetaSpire® PEEK and AvaSpire® PAEK demonstrate excellent chemical resistance, especially to aqueous systems including acids and bases. This allows them to withstand strong solutions of aqueous caustic solutions like sodium hydroxide, which has become one of the preferred methods for sterilization against Creutzfeldt-Jakob disease.

Ingredients are often added to cleaners and disinfectants to improve surface wetting and reduce evaporation. Our experience has shown that these chemicals can have a more detrimental affect on plastics than cleaners and disinfectants by themselves. This is primarily due to improper dilution or insufficient rinsing. Be sure to follow the manufacturer’s instructions to optimize the performance of the plastic.
