  • The purpose of this work is to create low friction and low tack silicone surfaces without addition of coatings or lubricants but through alteration of the physical structure of the silicone surface. Low friction silicone is desirable in medical catheters where sliding polymer surfaces can impact surgical procedures and outcomes. Low tack is also desirable in peristaltic pump tubing where tackiness ofthe inner portion ofthe tube causes pumping performance degradation and eventual failure.
    Standard extrusion dies and mandrels for silicone rubber typically utilize highly polished surfaces which result in high surface friction and the propensity for self-adhesion. By micromachining grooved patterns onto the die and mandrel surfaces, contact area of the silicone tubes is significantly reduced, thereby reducing the sliding friction and tackiness ofthe silicone surface by more than 60%. This paper will explore the use of patterned surfaces for continuous extrusion of silicone rubber and quantify reduction in surface friction and tackiness.
