Tedlar® polyvinyl fluoride (PVF) products are a part of the DuPont fluoropolymer family. DuPont™ Tedlar® PVF products offer a unique balance of aesthetics while offering the durability of a fluoropolymer.

A zoned heater system is utilized and controlled by a solid-state processor. The impingement area, or leading edge, is kept warm continually melting impinging ice, or simply, "runs wet". The area just aft of this impingement area, or shedding zone, is kept below freezing causing the run back to freeze and collect as ice. During a de-ice cycle the voltage is increased raising the temperature of this aft shedding zone, releasing the ice bond and shedding the ice via aerodynamic force. Once power is removed from the heater the shedding zones immediately freeze and continue to collect ice until the next de-ice cycle. This system may take as little as 1 second per surface and only 33 seconds to deice the entire aircraft using a 60 second cycle.
