Medical PEEK-based resins
Solvay Advanced Polymers has announced that KetaSpire PEEK (polyetheretherketone) and AvaSpire modified PEEK have achieved ISO 10993 biocompatibility compliance for use in limited-exposure medical devices and instruments. Based on rigorous biocompatibility testing, KetaSpire PEEK and AvaSpire modified PEEK resins are said to demonstrate no evidence of cytotoxicity, sensitization, irritation or acute systemic toxicity as defined by ISO 10993:1.
KetaSpire PEEK is also said to be one of the industry’s most chemically resistant plastics and also offers excellent strength, superior fatigue resistance, and a heat deflection temperature up to 315¬∞C (599¬∞F). It can withstand more than 1,000 cycles of steam sterilization without any significant loss of properties and is also compatible with other sterilization methods, including ethylene oxide, vaporized hydrogen peroxide, and gamma radiation.
