| TROGAMID® Care grades represent a range of both amorphous and microcrystalline transparent polyamides for processing via extrusion or injection molding. 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. 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. All advantages at a glance High transparency High chemical resistance Very good stress crack resistance UV resistance High dynamic load-bearing capacity Easy processability & colorability Free of BPA&& |
