Duratron® LSG PEI


The stock shape is 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- & 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.
