Eastman TRITAN™ copolyester

The future looks clear for blood contact devices. Health care professionals need a clear view of blood contact components to detect entrapped air, thrombosis, blood leakage, and other critical conditions. Lives depend on it.

Eastman Tritan™ copolyester is an innovative polymer with durable clarity in the face of rigorous health care environments. Tritan offers a balance of chemical resistance and impact strength, and is made without BPA, – all advantages over other engineering thermoplastics. Tritan adds value by improving reliability and safety, and inspiring clinician confidence in applications including:

Surgical devices:

  • Oxygenators
  • Bubble traps
  • Hematological reservoirs
  • Housings for hematological filters
  • Housings for cardioplegia filters
  • Connectors and stopcocks

Blood management devices:

  • Centrifuge bowls
  • Blood separation cassettes
  • Blood microfilters

Renal Dialysis devices:

  • Hemodialysis systems and accessories
  • Peritoneal dialysis systems and accessories
  • Filters
  • Dialyerzers
  • Connectors

Tritan stands up to blood, lipids, disinfectants, and sterilization.

Medical device manufacturers are under greater pressure than ever to provide innovative products that can withstand sterilization, medical disinfectants, powerful new drugs and carriers, and other chemicals.

  • Parts made with Eastman Tritan™ copolyester retain transparency after sterilization—including gamma or electron beam (e-beam) irradiation, and ethylene oxide (EtO) sterilization.

  • Best-in-class chemical resistance helps devices retain aesthetic and functional integrity after sterilization and exposures to blood, lipids, aggressive medical disinfectants.

  • Compatibility of Tritan with solvents and adhesives provide greater flexibility for secondary processes and solvent bonding of PVC or polyurethane tubes with device connectors.

  • Tritan is made without bisphenol A (BPA), halogens, or ortho-phthalates.

  • Tritan can reduce fibrinogen adsorption, compared with other polymers.

Clear advantages for processing, too.

Consistent high-quality Eastman Tritan™ copolyester can eliminate the secondary annealing step required to reduce stress cracking issues in some devices made with polycarbonate (PC). This can reduce processing bottlenecks, improve yield, and reduce overall system costs:

  • Good resin flow and easy release

  • Reduced black specks and flow marks

  • Greater flexibility for solvent bonding and other secondary operations

  • Excellent impact strength—especially valuable for devices with multiple ports
