Salomon Warm and Cold Skis, both skate and classic, have bases and ski molds designed for the characteristics of warm and cold snow. Warm is designated as -8C (17F) and warmer. Cold is designated as -5C (23F) and colder.
All Salomon ski bases are made with Ultra high molecular weight polyethylene (UHMWPE). Salomon's Equipe 10 Warm bases have more surface area to absorb more warm snow wax, than the cold base that are denser to reduce cold dry snow friction. Each base's exact properties are achieved by mixing various additives in various proportions to the UHMWPE.
Two of the additives that Salomon specifies are Salomon's proprietary Zeolite, as well as Carbon Black. Zeolite is a mineral used in many industries both as a sieve and as a sponge. Zeolite has a very regular structure that allows it to act as a sieve to keep out dirt particles over a certain size, while its ultra porous structure allows it to act like a sponge actively absorbing wax. Zeolite also maintains its uniform structure under extreme heat, allowing bases with Zeolite to be less prone to seal (close) when exposed to heat from waxing. Salomon's warm bases have more Zeolite than the cold base. The warm bases also have more carbon black in them then cold bases. Carbon black (often wrongly called graphite) is used for its very high surface area to volume ratio.
The warm and cold bases also have specific structure for warm or cold snow crystals and moisture content. For extreme wet conditions you can press in a hand structure above the warm grind. In cold conditions below -12C we reduce the cold structure with a metal scraper.
Equipe 9, 8 and JR racing skis use a universal base mixture and universal grind.
Not only are Salomon Warm and Cold bases different but so are the warm and cold ski molds.
