Ski wax is a material applied to the bottom of snow runners, including skis, snowboards, and toboggans, to improve their coefficient of friction performance under varying snow conditions. The two main

Polytetrafluoroethylene is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is heat resistant and chemically inert. The commonly known brand name of PTFE-base

…generation for lubrication, wear resistance in cold snow, and hydrophobicity to minimize capillary suction. These attributes are readily achievable with a PTFE base, which diminishes the value added by glide waxes. Lintzén reports that factors other than wax are much more important in reducing friction on…
