The Duratron™ LSG PEI stock shapes are also 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 use in wetted contact applications in bioprocessing.
Combining biocompatibility with peak performance, Duratron™ LSG PEI exhibits outstanding mechanical, thermal, electrical properties, as well as very good resistance to hydrolysis and chemicals.
Duratron™ LSG PEI components are also sterilizable by means of steam (autoclave), dry heat, EtO (Ethylene Oxide), plasma and gamma and X-ray irradiation. Due to these properties, Duratron™ LSG PEI is an excellent candidate for applications in the medical and bioprocessing fields such as trial implants and radiotherapy applicators.
