WEB EXCLUSIVE: As medical catheters get thinner and thinner, it becomes more difficult for unfilled TPEs and TPUs to provide the balance of stiffness and flexibility needed to insert the devices and thread them through long, complex vascular paths. That problem reportedly has been solved by use of nanoclay particles in new NanoMed TPE compounds from Foster Corp., Putnam, Conn. Crosslinking can be added to the nanocomposites, if necessary. Foster has developed formulations based on TPUs, soft nylons, and PEBA elastomers (Arkema’s Pebax). For example, only 9% by weight of nanoclay doubles the flexural modulus of Pebax.
