Multiple Layer Tubing-Co-Extrusion

Multiple Layer -Co-Extrusion

Co-extruded multi-layer tubing,the extrusion of material is done simultaneously to produce multi-layer/Co-extruded tubing, including durometer, color, opacity, radiopacity, or tensile strength, to provide custom catheter solutions. 

The most common application is medical extruded tubing with radiopaque stripes visible under x-ray. This is accomplished by encapsulating stripes containing a filler visible under x-ray within the wall of the tubing. 

Typical fillers include these compounds, which can be used in various concentrations to enhance radiopacity.
