Eastman Tritan™ copolyester: Innovative properties for medical devices

Eastman Tritan copolyester offers a unique blend of processing and performance properties, including clarity, toughness, and heat and chemical resistance. It can also often be substituted into existing molds with minimal adjustments to processing parameters. This total balance of performance and processing gives Tritan advantages and design flexibility over many other commonly used polymers. Some qualities that make Tritan an excellent choice when it comes to molding parts for the medical market include:
  • Toughness: Exceptional toughness and durability. Medical device housings made with Tritan are impact- and shatter-resistant and have the ability to withstand extreme conditions.
  • Clarity: Outstanding clarity and color retention before and after gamma and e-beam sterilization.
  • Chemical resistance: Maintains part integrity when exposed to a wide range of harsh chemicals and disinfectants. This excellent chemical resistance also means improved ESC resistance during solvent bonding and other secondary operations.
  • Heat resistance: Higher level of heat resistance, which some devices require to deliver their intended performance or for accelerated aging validation.
  • Reduced scrap rates: Less defects due to black specks, flow marks, cracking, and breakage.
  • No annealing required: Greater throughput and higher yield.
  • Sustainability: Made without BPA, halogens, or ortho-phthalates.
