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.
Envalior’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:
