Visualisation of devices in surgical procedures is vital for the success of the operation. Materials are modified to make them radiopaque and therefore visible using techniques such as X-ray fluoroscopes. There are a number of design issues that Clariant formulation know-how can solve.
Thin wall sections require higher density fillers to be radiopaque. Clariant offers a range compounds with different filler options e.g. barium sulphate, tungsten, Bismuth subcarbonate;
Complex multi-wall extrusion processes used in catheters require excellent surface finish. Clariant’s dispersion and processing know-how helps to achieve high quality surfaces. Lubricants can be included to further enhance extrusion and surface finish.
Several different types of resins are used including PP, TPU, PEBA. Clariant offers radiopaque compounds in a wide range of resins where ingredients have been pre-tested to USP parts 87 and 88 for Class VI devices and /or ISO10993.
Colors? Clariant provides the radiopaque compounds in a range of colors using the standard USP /ISO range or custom color to your requirements.
