Biomerics Elast-Eon™ E5-325 Aromatic Polyether Silicone Thermoplastic Polyurethane
Categories:	Polymer; Thermoplastic; Polyurethane, TP
Material Notes:	The Elast-Eon™ family of polymers combines the advantageous properties of both polyurethanes and silicone rubbers into a single material. These materials exhibit the physical and mechanical performance of polyurethanes and a biological stability that surpasses rigid biostable polyurethanes. Elast-Eon™ polymers are widely accepted as being the most biostable of all polyurethane materials and as such are being used in long-term implantation. Elast-Eon™ may be used in applications including: CRM Devices (e.g. Pacemaker) Neurostimulation Devices Electro Signaling Devices Breast Implants IUDs Implantable Joint Interface Coating Stents Ear Tubes Heart Wall Graft Information provided by Biomerics
