Sultron™ LSG PSU (Life Science Grade) stock shapes are made from unfilled Udel™ PSU resin that is pre-assessed for bicompatibility. 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 and wetted contact applications in bioprocessing.
Sultron™ LSG PSU shapes exhibit great mechanical, thermal and electrical properties. In addition, good hydrolysis resistance makes components resilient against repeated autoclaving cycles as well as other sterilization methods such as dry heat, EtO (ethylene oxide), plasma and gamma irradiation.
Because of these properties, as well as the material’s visual transparency, Sultron™ LSG PSU components are great candidates for applications in the medical and bioprocessing fields such as applicators, manifolds, steam cleaning equipment inserts and valves.
