Low-Friction Material Solutions for Catheter Delivery Solutions

An important property for medical devices and catheters is the ease with which they can be inserted into the body lumens and then removed after the device has performed its required function. Therefore, it is desirable to have the least amount of friction as possible between the device/catheter polymer and soft tissue interface.

Most polymers that have low friction properties such as fluoropolymers and HDPE also have low surface energy, which means that they often require surface modification such etching or the use of adhesives for bonding purposes during co-extrusion, reflow and over-molding operations.  ProPell™ low-friction additive is melt blended with different base polymers such as PEBA, TPU and Nylon to successfully reduce their coefficient of friction without considerably affecting the desired mechanical and adhesion strength properties.
