Whether in professional or recreational skiing, waxing skis and snowboards is crucial for smoother gliding and higher speeds. Typically used products contain per- and polyfluorinated alkanes, known as PFAS, some of which have shown health risks in animal tests. Consequently, the EU has set very low limits for these substances, and the International Ski Federation (FIS) and the International Biathlon Union (IBU) have completely banned the use of fluorinated alkanes in their competitions. LZH scientists, in collaboration with ZIPPS Skiwachse GmbH from Waldbrunn, have researched an alternative: "Green wax" combined with a novel microstructure on the surface is designed to provide skiing enjoyment without fluorine.

Lasered microstructures for speed

As part of a research project, LZH researchers developed a method to create a specific structure of the ski surface. Using a laser, they introduced microstructures into the ski surfaces. Combined with the newly developed fluorine-free ski wax by ZIPPS Skiwachse GmbH, these two innovative changes ensure a pleasant skiing experience, reduced friction, and higher speeds.

Tested by professional athletes

The performance of laser-structured skis was successfully tested on snow by experienced professional skiers, with the German Ski Association serving as an official test partner.
