Ketron® LSG CA30 PEEK

This 30% carbon fiber reinforced grade combines even higher stiffness, mechanical strength and creep resistance than Ketron LSG GF30 PEEK blue with an optimum wear resistance. Ketron LSG CA30 PEEK stock shapes have also been successfully type tested for their compliance with both United States Pharmacopeia (USP) and ISO 10993-1 guideline requirements for Biocompatibility Testing of Materials, and they come with full traceability from resin to stock shape. These features, added to an excellent sterilizability by means of steam, dry heat, ethylene oxide, plasma and gamma irradiation, make Ketron LSG CA30 PEEK stock shapes very suitable for applications in the medical, pharmaceutical and biotechnology markets.

Product Overview.

• Very high maximum allowable service temperature in air (250 °C continuously, up to 310 °C for short periods of time)
• High mechanical strength, stiffness and creep resistance, also at elevated temperatures
• Excellent chemical and hydrolysis resistance
• Excellent wear & frictional behaviour
• Very good dimensional stability
• Excellent resistance to high energy radiation (gamma- and X-rays)
• Inherent low flammability and very low levels of smoke evolution during combustion  

Engineering Notes.

The stiffness of all PEEK grades drops off significantly and expansion rate increases above its glass transition temperature (Tg) of 150 °C (300 °F). A material like Duratron^® PAI would be better suited for close tolerance bearings or seals operating at temperatures higher than 150 °C (300 °F
