Complex extrusions open up design, quality and performance possibilities for medical tubing products, such as catheters, wound drains and hemodialysis tubing.

Silicone is a proven material of choice for medical devices because of its purity and biocompatibility. It is also highly customizable, allowing it to be optimized for a wide range of devices that require radiopacity, conductivity and physical properties such as high tensile strength.
HCR silicone’s unique green strength — the strength of rubber in its unvulcanized state — allows for highly complex geometries in continuous extrusion processes, setting it apart from other types of polymers, such as polyurethanes, thermoplastics and room temperature vulcanizing (RTV) silicones. Used with a geometric transition extrusion process, such as Trelleborg’s GeoTrans, HCR extrusions can change cross-sections dramatically, opening up new possibilities in a wide range of medical devices, including wound drains, catheters and hemodialysis tubing.
