Ketron® LSG PEEK

Ketron LSG PEEK stock shapes (colours: natural, black) are produced from selected batches of PEEK polyetheretherketone resin. This material exhibits a unique combination of mechanical properties, temperature and chemical resistance. The composition of the resin used for the production of the Ketron LSG PEEK stock shapes complies with the regulations that apply in the Member States of the European Union (Directive 2002/72/EC, as amended) and in the United States of America (FDA) for plastic materials and articles intended to come into contact with foodstuffs.

Ketron LSG 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 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).
