Sugar based de-icer used in aviation

Market leader uses Susterra proponediol in de-icing formulation

Fight the winter cold! At least as far as de-icing and anti-icing fluids go, global market leader Kilfrost now offers an alternative made with renewavble resources. The new de-icing product DFSustain uses Susterra propanediol from DuPont Tate & Lyle Bio Products as a corn sugar-based alternative to petroleum-derived propylene glycol.

Susterra propanediol can be used in applications such as deicing and heat transfer fluids and as a base for engine coolants where stability over a range of temperatures is important.

DFsustain and has the potential to use up to 40% less energy in manufacturing than more traditional fluids. “Not only does the new product have serious green credentials, but it outperforms all existing propylene glycol de-icers and can cope with temperature up to -40°C,” said Kilfrost Chief Executive Gary Lydiate.

Flybe, Europe’s largest regional airline, is the first in the world to use DFsustain, which the company estimates has the potential to further significantly reduce the airline’s carbon footprint.

Kilfrost enjoys a diverse customer-base across 50 countries and five continents. With facilities in the UK, Europe, North America, and Japan, the company is able to offer a precise logistics solution 24 hours a day, whatever the conditions.
