DUKE Extrusion can provide polyimide tubing that is custom tailored to the unique needs of your application. Our polyimide medical tubing is commonly used in high-pressure applications, such as inflation lines for balloon catheters. Polyimide tubing is also commonly used for electrical isolation of conductive elements, among countless other applications.
What is Polyimide?
Polyimide is a thermoset material with a high operating temperature range, excellent tensile strength, and a high modulus. It does not melt when fused with other thermoplastic materials commonly used in catheter manufacturing. For these reasons, polyimide tubing is an ideal material for incorporation into composite tubing with highly specialized functionality.
We can provide polyimide tubing with round- or oval-profile lumens, as your application requires.
Polyimide Lined Lumens
DUKE Extrusion can add polyimide lined lumens to any of our extruded tubes. Polyimide linings reduce the coefficient of friction along the inside of the tubing, making it easier for components or actuation cables to slide through the tube with reduced friction. We have the polyimide processing capabilities to provide linings as thin as 0.0002”.
Like our PTFE lined lumens, polyimide linings can be added to single or multi-lumen tubing. Multi-lumen tubing can have any number of individual lumens lined with polyimide. Polyimide lined lumens in multi-lumen extrusions are laminated to other thermoplastic materials, such as polyurethane, polyethylene, Nylon 12, Pebax®, or to Duke’s proprietary resin formulas such as PebaSlix™, PolySlix™, NyloSlix™, and FluoroSlix™.
