Silicone Extrusions – our GeoTrans® Process Extrusions
Trelleborg Sealing Solutions patented GeoTrans® processes are synonymous with silicone extrusion innovation. GeoTrans® pioneered the technology of movable die and mandrels allowing us to produce tubes with transitional geometry.
Here are just some of the extruded designs possible with our patented GeoTrans® technology:
GeoTrans® Extruded Balloon
Silicone balloons are common to many medical devices. A preformed balloon segment is typically bonded to a catheter shaft at a position where a small opening allows inflation by saline or air. GeoTrans® balloons are formed in a single extrusion step as an integral part of a catheter shaft eliminating significant costs associated with secondary operations and inspections. We can produce GeoTrans® balloons in a range of sizes and inflation pressures to fit your requirements.
GeoTrans® Material Transition
Our GeoTrans® Material Switch technology allows for the transition from one silicone material to another over the length of an extrusion. The two silicones may have different mechanical properties, additives, color, opacity, radiopacity, and durometer. The typical application for this technology is a stiff silicone catheter with a soft silicone tip to facilitate installation in the body while enhancing patient comfort.
GeoTrans® Single to Multi-Lumen
With our GeoTrans® lumen transition technology, we produce tubes in which the single lumen tube transitions into a multi-lumen tube.
GeoTrans® Stop Lumen
Our Geo-Trans® Stop Lumen Tubing eliminates the need for secondary operations such as applying a room temperature vulcanized silicone plug to close the lumen. Our single or multiple lumen tube can have one or more lumens stop and restart, depending on requirements.
GeoTrans® Bump Tapered Tubing
Our Bump or Tapered GeoTrans® tubing is used for applications requiring a variable outer diameter and either a constant or variable inner diameter. The variations and applications are endless. The bump/tapered tubing can be used for a catheter where the intravenous section is smaller, minimizing disruption in blood flow.
GeoTrans® Advanced Wound Drain Technology
GeoTrans® wound drains set the industry standards for function and reliability. Using patented GeoTrans® processes, we manufacture and stocks various sizes of both the 4 channel and saw-tooth design.
