Evonik TROGAMID® CareMX73 Polyamide
Categories: Polymer; Thermoplastic; Acrylic (PMMA)

Material Notes: TROGAMID® Care grades represent a range of both amorphous and microcrystalline transparent polyamides for processing via extrusion or injection molding. Durable: Microcrystalline TROGAMID® Care MX is the material of choice for all applications dealing with pharmaceutical formulations, lipids or aggressive disinfectants, since it exhibits an exceptional resistance towards chemicals and stress-cracking. Examples include fluid and drug delivery equipment such as stop-cocks, dialyzer parts, housings, covers or hearing aids. The high mechanical stability of amorphous TROGAMID® Care MT50 predestines the material for applications requiring a high modulus but retaining impact resistance which includes e.g. dentures, parts for monitoring and imaging devices or durable medical equipment. It comprises one of the highest tensile moduli compared to other transparent polyamides. Functional The antibacterial TROGAMID® Care MX73-A was designed to protect medical devices from surface bacterial colonization, while preserving its outstanding resistance to chemicals and stress-cracking as well as transparency. ISO 22196 tests conducted with E. coli and S. aureus showed a reduction of the viable cell count of more than 99.99%, each. TROGAMID® Care MX73-L is a transparent specialty grade for applications involving laser welding and laser marking. Though appearing transparent and colorless, it absorbs laser radiation, wherefore the combination of TROGAMID® Care MX73 and MX73-L enables the connection of two transparent parts via laser-welding, omitting exposure of the materials to extensive heat treatments or usage of adhesives. Target areas of application for TROGAMID® Care MX compounds include fluid and drug delivery systems, surgical instruments, housings, monitoring and imaging devices and durable medical equipment.
