Custom Profile Co-Extrusions
Co-extrusion is the combination of two materials, extruded at the same time, into a single tube. The materials can be arranged in concentric tube-on-tube configurations, or with striping in a single lumen. In multi-lumen coextrusions, we can isolate materials to specific regions of the tubing’s cross-section.
Stripes in co-extrusion tubing are used for alignment, improving radiopacity, and identification. Stripes also allow light to pass through a specific portion of the tubing and enhance the physical properties of a particular section of the tube, such as lubricity.
Tube-on-tube concentricity in coextrusion tubing is used to combine the beneficial properties of two different materials. For example, a high pressure-resistant material under a more durable, puncture-resistant outer layer for greater durability.
Duke Extrusion can manufacture custom tubing with profile coextrusions that meet your specific needs. To get started, please specify the inside diameter (I.D.), outside diameter (O.D.), materials, and the thickness, width, and/or percentage of each material. Materials should be relatively similar in properties—we will work with you to determine the best materials for your unique application.
We can produce custom co-extrusions with separate material layers as thin as 1/1000th of an inch. We can provide specialty profiles, such as squares, open channels, and others. We can combine coextrusions with our taper/bump tubing and multi-lumen manufacturing capabilities as your designs require.
