How Does De-Icing an Aircraft Work & Why Is It Important? | Safewing™

How does the aircraft de-icing procedure look like? What are the aircraft deicing fluid types and why is de-dicing an aircraft even important? In this video we answer all these questions on de-icing aircrafts and give you more insights on Clariant's aircraft anti ice system.

02:55 How Sustainable Are De-Icing Fluids?
For safety reasons aircraft wings have to be free of ice and snow - Worldwide, more than 41 million airplanes with over 4 billion passengers take off in the course of a year. During the winter months, ice and snow on the wings can interfere with lift, which can lead to crashes. To prevent that, special fluids are used to deice planes and protect them from reicing before take-off. They are colored differently to facilitate telling them apart and see whether they have been spread evenly.
Clariant is one of the largest manufacturers of deicing and anti-icing fluids in the world. With the Safewing™ portfolio Clariant offers different kinds of deicing fluids (Type I) and anti-icing fluids (Type II and IV). The deicing fluids are used to remove ice and snow from planes by spraying the heated fluid with high pressure onto the surfaces. Type II and type IV anti-icing fluids are used to coat aircraft parts with a viscous layer that protects against the new formation of ice, greatly extending the time window for the take-off of the aircraft. Before the aircraft leaves the ground, their viscosity drops significantly due to various mechanical forces, thus flowing off.

▬ Safewing™ Aircraft De-Icing ▬▬▬▬▬▬▬▬▬▬
Safewing™ is the effective solution against snow and ice. Even in extreme winter conditions, runways need to be clear and the surfaces of aircraft must be are free from ice and snow before take-off. This is why Clariant has developed De-/Anti-Icing Fluids, which fulfil all international requirements. We apply exacting standards to the quality and reliability of these products. In attaining these standards, environmental protection is given equal priority.
Clariant has wide-ranging expertise in research, development and environmental protection. With over 40 years of de-icing industry experience, our aircraft de-icing products ensure the safety that people depend on.
▬ Environmental Impact of Anti- and De-Icing Fluids ▬▬▬▬▬▬▬▬▬▬
De- and anti-icing fluids are based on either ethylene or propylene glycol. While glycols are easily biodegradable, the degradation process uses up large amounts of oxygen thus potentially harms aquatic organisms. Flight cancellations due to lack of deicing fluid are another, completely different challenge due to insufficient stocking and/or logistics.
All Clariant deicing and anti-icing fluids have a superior environmental profile thanks to their fully biodegradable additive packages and low surfactant content. Furthermore, Clariant has developed a special on-site recycling program that ensures that up to 70 percent of the glycol can be re-used in the production of deicing fluids. Due to its global presence, Clariant has the logistic capability to provide regional airports with very short lead times.
