Material Notes:
A hard, colorable, specialty, non-hygroscopic thermoplastic vulcanizate (TPV) in the thermoplastic elastomer (TPE) family. USP Class VI Certificates of Compliance exist for representative samples of our medical grades. Prior to release, each medical grade lot undergoes a Cytotoxicity study using the ISO elution method and a Physico-Chemical - Elastomeric Closures test for heavy metals such as lead. This grade of Santoprene 8000 TPV is shear-dependent and can be processed on conventional thermoplastics equipment for injection molding, extrusion or blow molding. It is polyolefin based and completely recyclable.Key Features: This grade meets the USP (U.S. Pharmacopeia) Class VI requirements for plastics.Additionally some ISO 10993 tests have been conducted.Each medical grade undergoes annual testing for cytotoxicity and heavy metals.Drug master file maintained with the FDA.EU and China RoHS compliant.Applications:Medical – Soft Touch Grips, USP Class VI Seals and GasketsUses:Medical/Healthcare ApplicationsProcessing Method: Blow Molding, Extrusion Blow Molding, Injection Blow Molding, Injection Molding and Multi Injection MoldingAvailability: Africa & Middle East, Europe, North America, Asia Pacific, Latin America and South AmericaInformation provided by ExxonMobil Chemical
