Definitions

  • the invention relates to a ski base based on polyethylene, a process for its preparation and its use.
  • fluoropolymers such as polytetrafluoroethylene
  • fluoropolymers have only moderate wax absorption, since the diffusion of the wax is extremely slow due to the high crystallinity.
  • the present invention is therefore based on the object of specifying a ski base which is both compared to known ski bases improved wax absorption as well as improved sliding behavior on the snow.
  • ski covering according to the invention based on polyethylene, which is characterized in that it contains a fluorine-containing additive in an amount of up to 5% by weight.
  • This fluorine-containing additive can advantageously be one based on a fluorine oil, a fluorine wax, or a partially fluorinated one
  • Hydrocarbon or a fluoropolymer because these additives increase the diffusion of ski wax, the use of which is particularly important in ski racing.
  • the ski covering according to the invention advantageously has a fluorine content of 0.01 to 2% by weight, preferably 0.5 to 1% by weight. This fluorine content ensures problem-free further processing of the ski surface, for example with abrasives.
  • the ski covering according to the invention can advantageously be produced by adding a fluorine-containing additive to the extent of up to 5% by weight to the starting material based on polyethylene, which is known per se, such as screw extrusion, piston extrusion or press sintering. Due to the high melting point of fluorine compounds, these can also be used in high-temperature processes, such as press sintering, without changing their structure.
  • ski covering according to the invention can advantageously be used
  • PVDF polyvinylidene fluoride
  • HDPE high-density polyethylene
  • PTFE polytetrafluoroethylene
  • UHMW-PE ultra-high molecular weight polyethylene
  • a ski covering profile is produced, the cross section of which can be dimensioned by the shape of the extruder nozzle.
  • Example 3 30 ultra high molecular weight polyethylene (UHMW-PE) 3% by weight of a
  • This powdery mixture is in a
  • This ski base is particularly suitable for the manufacture of alpine and cross-country skis.
