How thick must a wax film be? The Latest Research from Matthias Scherge

  the full-length article here.   Abstract: “With physical/chemical surface analytics the layer thickness of wax was measured. The measurements prove that wax as block or powder penetrates the ski base only a few 100 nm and as spray only a few 10 nm. The wax does not use any pores in the ski base but entangles with the molecules of the polymer to form a compact sliding layer. The durability of this layer depends...

An Interview with Matthias Scherge: Helping FIS Jump the Fluoro-Free Hurdle

Matthias Scherge is the director of the Fraunhofer  Microtribology Center in Germany. As one of the major European research institutes specializing in industrial lubricants, Scherge and his colleagues have a hand in the ski wax game. Currently, Scherge is assisting the International Ski Federation (FIS) to implement its fluoro-free policy. Specifically, they are determining the thresholds at which a positive or a negative test will be triggered when testing a ski base for fluoros.   Scherge...

Are Fluorinated Ski Waxes Really the non plus ultra?

Last November, the International Ski Federation announced in a press release the banning of fluorinated waxes starting with the 2020-2021 race season.  FIS states, “The use of fluorinated ski waxes, which have been shown to have a negative environmental and health impact were banned for all FIS disciplines from the 2020/2021 season.” Behind the scenes, the transition to fluoro free racing has begun both in Europe where the majority of World Cups are held, and...
