Sultron® LSG PSU


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.

Intended Use

Sultron® LSG PSU is only intended for applications in which the duration of contact with human body tissue is limited to less than 24 hours, or wetted contact applications in bioprocessing.

Furthermore, LSG materials are not intended for use in the manufacture of medical devices that will be permanently implanted in the body, nor are they intended for use in life-sustaining medical devices.
