Engineering Materials

Developing advanced catheters that improve patient outcomes

Polyether Block Amide (PEBA), widely used in catheters poses reliability issues in demanding catheter applications. The material absorbs moisture levels that may cause tubing to change dimensions or lose stiffness – making it more difficult to predict how final parts will perform in clinical environments. Manufacturing with PEBA also produces gel defects that create stress risers in thin-walled components and potential points of failure.

Selecting PEBA can also lead to quality issues during production. Catheter tubing made of the material tends to show high variation in extrusion behavior, which yields high scrap rates. To protect and grow your business, you need to select a high-performance material that minimizes any risk to patients, enables you to reduce costs, and is well-suited to catheter production processes.  

Decrease material related recalls by making differentiated products with Arnitel® Care

DSM’s Arnitel® Care is specially engineered for manufacturing soft, durable medical devices that excel in high moisture and high-temperature conditions. The material combines high flexibility with the strength of rubber, due to its unique hard polyester and soft amorphous link structure. Key benefits for catheter manufacturers include:

  • Compliance with FDA food contact, USP Class VI and ISO 10993-5/10 standards
  • Stiffness tunable between 20 and 1000MPa for catheters with strict performance needs
  • Extremely predictable extrusion behavior, ensuring high repeatability and reducing scrap
  • Best-in-class snap back memory to prevent part deformation
  • Outstanding thermal stability during assembly and in use
  • Eliminates the risk of gel forming at bonding points
  • High to low durometer grades that are easily welded and glued together
