Ineos ABS Lustran® 308 ABS, Medical Grade (discontinued **)
Categories:	Polymer; Thermoplastic; ABS Polymer; Acrylonitrile Butadiene Styrene (ABS), Molded
Material Notes:	Lustran® ABS 308 resin is a low gloss, easy-flowing grade of ABS (acrylonitrile butadiene styrene). This injection molding grade offers a good balance of rigidity, impact strength, and abuse resistance. The resin is available in natural (000000). Lustran® ABS 308 resin is designed for applications requiring a good balance of physical properties and a low-gloss appearance. Typical applications include components of intravenous (IV) systems, diagnostic test kits, and surgical instruments. As with any product, use of Lustran® ABS 308 resin in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability. Lustran® ABS 308 resin is designated as “medical-grade” and has met the requirements of the FDA-Modified ISO 10993, Part I “Biological Evaluation of Medical Devices” tests with human tissue contact time of 30 days or less. Regrind must not be used in medical applications requiring biocompatibility. Lustran® is now a product of INEOS Styrolution. Information provided by the manufacturer.
