In 2018/2019 there was the discussion about the contamination in the waxes, so the regulation 2020 was developed. Since then we focus on the Regulation 2020 and in the future only fluorine free.
All products that have the label "Regulation PFC 2020" contain the C6 chemistry. All fluorine free products are marked with the label "TripleX" and "PFC Free".
All products which do not carry a label are with the old C8 chemistry, these should no longer be available in the sport shops and no longer be used.
