Medical devices

For fluid administration and blood contact

Quality medical devices start with quality polymers. Medical grade Eastman polymers are making a significant impact in key areas of medical innovation, driven by their unique chemical properties and Eastman's comprehensive, total-solutions approach. This approach integrates advanced material science, tailored product development and collaborative partnerships with customers to ensure the polymers meet the specific healthcare application needs.

Eastar™ copolyesters

Eastar 6763, MN005, MN006, MN210 and MN211 copolyesters meet ISO 10993 and/or USP Class VI biocompatibility requirements. Eastar formulations also deliver:

  • Brilliant clarity
  • Excellent color and property retention following gamma and e-beam sterilization
  • Chemical resistance to most medical solvents, including lipids and isopropyl alcohol (IPA)
  • Very good impact strength and toughness
  • Good processing characteristics

Individual Eastar copolyester grades offer unique advantages:

  • Eastar MN004 and MN006 can provide even greater advantages in dimensional stability and low shrinkage rates.
  • Eastar MN005 offers high flowability for thin-walled, intricate parts.
  • Eastar MN004 and MN006 are GREENGUARD Indoor Air Quality Certified®.

Tenite™ cellulosics

Tenite 360E0096914 and 360E4861312 are known for an excellent balance of toughness, surface gloss, clarity and warm feel. Select formulations of the Tenite propionate family meet ISO 10993 and/or USP Class VI biocompatibility requirements and offer:

  • Excellent resistance to fats and chemicals, making them suitable for solvent bonding and other processing methods
  • High-flow processing capabilities while maintaining chemical resistance — a good choice for devices that require toughness but need thin walls or long flow lengths (cannulas, IV components, etc.)
  • High-performance cellulosics made from 100% renewable softwood trees harvested using sustainable forestry management practices (40%–50% renewable content by volume)

Renal device applications

Premature cracking and breakage of renal device housing can lead to higher costs and create safety risks for patients. Using quality materials like Eastman Tritan™ copolyesters, with their glasslike clarity and toughness, helps mitigate these issues and improve care quality. With housing made from Tritan:

  • Healthcare professionals clearly see membranes, aiding detection of air bubbles or leaks.
  • Patients and families see a clear lifesaving device.
  • Clarity, color and function remain after gamma or e-beam sterilization.

A new generation of polymers

Tritan copolyester offers a balance of processing performance advantages over other engineering thermoplastics and polyolefins. It helps boost hospital and clinic confidence while reducing system costs in renal device applications. Tritan features:

  • Clarity and durability in housing, protecting hollow fiber membranes
  • Chemical resistance to stand up to disinfectants and chemicals
  • Elimination of the annealing process, leading to increased throughput and yield

Hit your sustainability goals

Eastman understands many brand owners and manufacturers of renal devices are working toward sustainability goals — for the good of the environment, their brand reputation and their business success. Tritan copolyester is a material that can be molded into housing with a world of sustainability advantages:

  • Toughness that enables thinner-walled housing designs
  • Durability that allows for reduced packaging
  • Free from BPA, halogens and ortho-phthalates
  • Chlorine-free to minimize hazardous pollutants during incineration
