KETRON ® PEEK LSG stock shapes are produced from selected batches of Victrex ® PEEK PolyEtherEtherKetone resin. This material exhibits a unique combination of mechanical properties, temperature and chemical resistance. The composition of the resin used for production of the KETRON ® PEEK-LSG 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 PEEK 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-LSG stock shapes very suitable for applications in the medical, pharmaceutical and biotechnology markets.

Ketron PEEK-LSG is available in sheet and rod forms in  natural (a very light brown or tan)  and  black  colors.

Quadrant's PEEK-LSG 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 24 hours, or are intended to remain in contact with internal human tissue or bodily fluids for more than 24 hours, or as critical components of medical devices that are essential to the continuation of human life.
