Specialty Polymers for Reusable Devices
Radel® PPSU (polyphenylsulfone) is an incredibly tough, transparent plastic that can withstand more than 1,000 cycles of steam sterilization without any significant loss of properties. PPSU exhibits higher impact strength than polycarbonate (PC) and polyetherimide (PEI) and retains its toughness and strength over time. Its superior chemical resistance makes it highly resistant to commonly used cleaners and disinfectants over a broad temperature range. Opaque and transparent colors as well as with glass fiber reinforced grades are available.
Veradel® HC PESU (polyethersulfone) is a durable, transparent polymer with heat resistance on par with Radel® PPSU. The material’s high flow rate makes it particularly suited for injection molding thin-walled parts and components with complex geometries. Its stiffness is the highest of all medical-grade sulfone polymers.
Udel® PSU (polysulfone) is a rigid, high-strength, semi-tough, transparent plastic that offers higher heat resistance and better hydrolytic stability than polycarbonate (PC). PSU retains its good mechanical properties when exposed to oxidizing agents, steam and other sterilization techniques. Opaque and transparent colors as well as glass fiber reinforced grades are available.
Ixef® PARA (polyarylamide) uniquely combines high stiffness with an ultra-smooth finish that’s on par with painted metal. Gamma-stabilized colors can be sterilized using gamma radiation without any significant change in appearance or loss of mechanical properties.
AvaSpire® PAEK (polyaryletherketone) is a versatile family of proprietary formulations tailored to provide new and unique combinations of performance and value. AV-600 Series products deliver excellent chemical resistance, good impact strength and can withstand more than a 1000 cycles of steam sterilization. Glass-fiber and carbon-fiber reinforced grades are available.
KetaSpire® PEEK (polyetheretherketone) is one of the most chemically resistant plastics available and offers excellent strength, stiffness and fatigue resistance. PEEK can be used continuously in hot water or steam without significant loss in physical properties. Glass-fiber and carbon-fiber reinforced grades are available.
Based on biocompatibility testing as defined by ISO 10993:1, our healthcare plastics demonstrate no evidence of cytotoxicity, sensitization, intracutaneous reactivity or acute systemic toxicity. They can be sterilized using all conventional sterilization methods, including steam, ethylene oxide, vaporized hydrogen peroxide and gamma radiation.
