Navigating the complexities of compatibility with oncology drugs

The need to mitigate infection risks and enhance patients’ safety and comfort has significantly increased the demand for higher-performing plastics with improved chemical resistance. Many polymers commonly used in drug delivery devices simply do not hold up to modern oncology chemotherapies. After exposure to chemicals in the medical environment, devices made with these polymers can experience environmental stress cracking or premature failure in the presence of applied or residual stress.
 
Broken devices put patients at risk. What’s more, regulatory agencies may tell manufacturers to stop using certain materials when device performance or life cycle is compromised.
 
For these reasons, when you are choosing materials for your medical device, evaluating polymers for chemical resistance is key. Eastman Tritan copolyesters have excellent overall chemical resistance and other advantages that make them superior alternatives to polycarbonate (PC) or acrylonitrile-butadiene-styrene (ABS) for oncology drug delivery devices.
 
Tritan also offers compatibility with many popular sterilization methods and has outstanding hydrolytic stability. This balance of properties makes Tritan a great choice for IV system components, blood therapy devices, and any parts that face frequent disinfection.

Eastman Tritan™ copolyester—superior attributes for medical devices

Eastman Tritan™ copolyester is raising the bar for durability and cleanability in medical devices and housings. BPA-free Tritan’s attributes include exceptional clarity, toughness, improved heat and chemical resistance, and more. It’s also easy to process due to its unique chemical makeup relative to traditional thermoplastics. This blend of processing and performance properties provides greater advantages compared with other commonly used polymers. Available in clear and opaque formulations, Tritan offers many benefits to enhance innovative device designs:
 
Clear formulations of Tritan
  • Greater toughness, heat resistance, processability, and design freedom
  • Clarity, color stability, and functional integrity after sterilization
  • Outstanding chemical resistance to lipids, IPA, disinfecting agents, and bonding solvents and adhesives
 
Opaque formulations of Tritan
  • Excellent functionality and reliability for device housings
  • Compatibility with aggressive disinfection and the daily impact stresses that come with greater portability
  • Color and functionality following sterilization with gamma and e-beam irradiation
  • Reliable color matching
  • Flame-retardant properties (Tritan MXF121 copolyester)
    • Fire retardant—UL 94 V-2 rating @ 1.5 mm
    • Excellent resistance to chemicals and lipids
    • Meets hospital Environmentally Preferable Purchasing (EPP) guidelines—made without halogens or ortho-phthalate plasticizers
    • Clear and opaque formulations—color matching available
    • Excellent durability—high impact strength and toughness
    • Fast cycle times

Educating product managers on how plastics affect your brand
 

The material you choose for your medical devices can have a big impact on your brand’s image. In today’s healthcare environment, not all plastics can withstand exposure to the aggressive disinfectants being used in hospitals. If your device is showing outward signs of suffering from exposure to effects of disinfection, including yellowing, cracking, crazing, or paint peeling, it’s time to reconsider material selection.

 

Educating product managers about the attributes of different plastics can help better shape brand positioning. For example, cracks and crazes can lead to pooling of aggressive disinfectants and leakage into the sensitive electronics that make the device function. Choosing a more chemically resistant polymer prevents this by strengthening device durability and reducing maintenance time. As a result, the working life of the device increases and maintenance and replacement costs go down.

 

With this information, the product manager can position the brand as being resistant to the physical handling or moving of devices despite more frequent cleaning and use of harsh disinfectants. They can present brand devices as having a longer service life, keeping their “new” look longer, and being more durable. This positioning can also be used by hospitals and clinics, which can improve their image by purchasing more durable equipment that looks better because it is better.

 

By choosing materials with better quality and performance, manufacturers can help product managers position the brand as having those qualities as well.
