Promising high lubricity, superior chemical resistance, and excellent electrical insulating characteristics, PTFE is available to be selectively coated onto small diameter wire components such as pins, needles, and electrodes as well as plain wire. It also can be applied to tube sub-components for catheter and many laparoscopic applications. PTFE coatings boast excellent surface adhesion—an important attribute since many components are invasive items—and provide very tight tolerances with thicknesses from 0.0002 in.
