Customer Challenge PTFE (Polytetrafluoroethylene) is widely used in medical devices, electronics, and precision industrial applications due to its exceptional chemical resistance and low coefficient of friction. However, its extremely low surface energy makes it one of the most difficult polymers to print, bond, or coat.
