Blood Contact Systems

Until now, processing bottlenecks—annealing to reduce molded-in stress and black speck rejections, to name just a few—have been the unfortunate trade-offs for producing clear blood contact surgical devices from polycarbonate (PC) resin. Eastman Tritan™ copolyester can eliminate the secondary annealing step required to reduce potential stress cracking issues in PC as well as offer other advantages to improve yield while reducing overall system cost.

  • Good resin flow and easy release

  • Reduced black specks and flow marks

  • Consistent high-quality resins and processing flexibility, compared with batch-processed styrenics

  • Best-in-class chemical resistance to improve yield during secondary operations, such as solvent bonding of polyvinyl chloride (PVC) tubes with device connectors

  • Toughness to withstand the stress and strain demanded by common secondary operations

  • Higher toughness, allowing potential downgauging 

In addition to clear advantages in processability, blood contact devices molded from Eastman Tritan™ copolyester offer best-in-class resistance to blood, lipids, and a wide range of aggressive disinfectants and superior retention of color and clarity plus freedom from bisphenol A (BPA). All this makes Tritan ideal for many blood contact and blood management systems.

Improving products while improving sustainability

Eastman understands many brand owners and manufacturers of blood contact devices are working toward sustainability goals as a socially responsible company. This is good for the environment, good for business, and good for its brand image. Eastman Tritan™ copolyester provides a material that can be molded into parts with a world of sustainability advantages.

Eastman Tritan™ copolyester creates value advantages over PC and other materials by reducing total system cost without sacrificing performance and aesthetics while also offering more ways to enhance your "green" image. That means greater quality, more satisfied customers, and improved profit opportunities.
