Ketron™ LSG PEEK (Life Science Grade) stock shapes are made from unfilled PEEK resin. Both resin and stock shape are pre-assessed for biocompatibility for up to 24 hours contact with body and tissue according to USP VI and ISO 10993. Some color variations are also pre-assessed for wetted contact applications in bioprocessing.
Ketron™ LSG PEEK shapes exhibit high stiffness and mechanical strength. The components are also sterilizable by means of steam (autoclave), dry heat, EtO (Ethylene Oxide), plasma and gamma and X-ray irradiation, making this material an excellent candidate for applications in the medical and bioprocessing fields, such as endoscopes/laparoscopes, manifolds, valves, connectors, lids and adapters.
