100% fluorocarbon, high fluorocarbon, hydrocarbon, universal: the difference between these types of wax is the level of more or less fluorinated paraffins.

When the indication is Hydrocarbon or NF, it is a non-fluorinated paraffin "NF". A universal wax generally has a non-fluorinated paraffin for a snow temperature of about -5 degrees, which is a common temperature.

When the temperature rises and you slip badly the wet snow sticks on the ski-base. Iit is necessary to use a wax with the high fluorocarbon content.
