The findings reveal that Solvay’s Radel polyphenylsulfone (PPSU), Udel polysulfone (PSU), AvaSpire polyaryletherketone (PAEK), and KetaSpire polyetheretherketone (PEEK) retain excellent mechanical performance and stable appearance properties after 200 cycles of the Sterrad 100NX standard cycle. “The study confirms that our medical-grade polymers have strong compatibility with hydrogen peroxide gas plasma sterilization,” said Jim Hicks, technical marketing engineer for Solvay Specialty Polymers. “This further attests to Solvay’s broad high-performance material portfolio which meets the sterilization needs of the medical industry.”
Solvay’s Medical-Grade Polymers Retain Excellent Mechanical Performance after 200 Cycles of Sterrad 100NX Standard Cycle
Historically, the standard sterilization method for reusable devices has been steam autoclave, according to Hicks. However, the growing use of electronics and endoscopes, which are not compatible with the high-temperature environment of the steam autoclave, has increased the need for low-temperature sterilization techniques such as hydrogen peroxide gas plasma. As a result, Solvay saw the need to evaluate its medical-grade materials to build support data and confirm the capability and performance of its materials for the medical industry.
The recent testing examines the materials at higher cycles and under more aggressive conditions as compared to previous evaluations, according to Hicks. Solvay’s medical-grade polymers are also compatible with other typical sterilization techniques including ethylene oxide (EtO), gamma radiation, and steam autoclave.
Solvay’s medical-grade plastics lineup provides design engineers with the ability to create new products that offer metal-like performance in a lighter weight design, with the ease and flexibility of plastics manufacturing for applications such as instrumentation, reusable and single-use devices, medical equipment, and sterilization cases and trays.
