A study was conducted to extrude low friction and low tack microstructured surfaces on silicone rubber. Silicone rubber tubing was extruded using a 2-1/2' Davis-Standard extruder and a vertical HAV curing tunnel. The silicone rubber used to conduct the investigations was a standard 50 durometer platinum cured compound used for healthcare applications requiring high purity and biocompatibility. Tube-in-tube friction tests demonstrated the low friction characteristics of the inner diameter of the silicone tubing. The microstructured low friction silicone tube allowed the PTFE tube to pass all the way through which simulated catheter insertion procedures. Microstructured silicone tubing allowed PTFE to pass completely through and the PTFE tube was completely inside the microstructured silicone tubing in the middle sinusoid.
