KETRON ® PEEK-CLASSIX ® LSG PolyEtherEtherKetone stock shapes are produced from Invibio ® PEEK-CLASSIX ® white resin. This material exhibits a unique combination of mechanical properties, temperature and chemical resistance. The composition of the Invibio PEEK-CLASSIX White resin 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 PEEK-CLASSIX LSG 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 PEEK-Classix LSG stock shapes very suitable for applications in the medical, pharmaceutical and biotechnology markets.

Ketron PEEK-CLASSIX LSG is available in sheet and rod forms and is  white  in color.

Quadrant's PEEK-CLASSIX ® Life Science Grade should not be used for applications involving medical devices that are intended to remain implanted in the human body continuously for a period exceeding 30 days, or are intended to remain in contact with internal human tissue or bodily fluids for more than 30 days, or as critical components of medical devices that are essential to the continuation of human life.
