Webinar available on demand— Chemical resistance in fluid management systems

In case you missed this informative webinar on 11 May 2016, it is now available for you to watch whenever you choose. The webinar addresses in detail:
•  The need for chemical resistance in connectors, stopcocks, and filtration components
•  How engineering polymers compare for compatibility with drugs, lipids, and carrier solvents
•  How to use Eastman Tritan copolyesters in your fluid management components to improve patient safety

Some traditional polymers are incompatible with oncology drugs, carrier solvents aggressive, and frequent disinfection used to prevent hospital-acquired infections (HAIs). Some lack the rigidity to meet new ISO 80369 requirements.

 In this one-hour webinar, Tritan experts explain the increasing pressure on today’s medical devices—especially fluid management components and blood contact devices—to meet high performance standards for:
•  Patient safety
•  Performance expectations (aesthetics/functionality)
•  Portability and constant handling
•  Aggressive disinfectants, harsh pharmaceuticals, and carrier solvents
•  Sterilization (EtO, gamma irradiation)
•  Changes in ISO 80369/AAMI CN3(PS):2014 standards for small bore connectors across all fluid management platforms
•  Lifetime value
They also will discuss tests used to verify compatibility with disinfectants, harsh oncology drugs and their carrier solvents, and solvents used in fabrication and assembly.

Secondary Operations: Overmolding

The use of overmolded soft-touch materials is commonly employed to add both functional and decorative elements to articles produced from rigid thermoplastic elastomers (TPE). Eastman Tritan copolyester demonstrates excellent adhesion with commercially available TPE grades. Before selecting the TPE grade for use, work with either the TPE supplier or Eastman to choose a grade which is formulated for use with a copolyester substrate—and designing your part for successful results.  

Part design considerations:                 

  • Optimize part thickness and TPE thickness for adhesion and dimensional stability. TPE thickness in excess of the Eastman Tritan copolyester part thickness could result in warpage when you remove it from the mold. The typical rule of thumb recommends a substrate thickness twice that of the TPE.
  • Mechanical interlocks can be incorporated to improve TPE adhesion and promote part durability. Mechanical interlocks become particularly important with thin TPE layers or very demanding fitness-for-use requirements.
  • For designs incorporating soft-touch features on multiple surfaces, flow-through designs should be used to improve adhesion and durability.
  • To minimize the potential for peeling or delamination, the edge of the TPE should be flush with or below the level of the non-overmolded section of the rigid substrate. 
For more part design and specific processing information, consult the appropriate literature available from your TPE supplier.
Be sure to consider the specific end-use environment of the overmolded article when selecting the appropriate TPE grade to confirm that it means your specific fitness-for-use criteria.

Troubleshooting focus: warped or distorted parts
Warping or distortion beyond specification can occur to parts as they are ejected from the mold or after packing and shipping. The final defects can look similar, but their causes are very different. 

TMI TIP: Proper cooling is well worth the wait when processing copolyesters. Their relatively low flexural modulus gives them a greater ability to flex and rebound—and allowing the skin to freeze is the best way to ensure optimum results. For more information, watch the webinar Copolyester Processing Solutions
