Running surface for a winter sports apparatus, winter sports apparatus comprising such running surface, material composition for production of such running surface, use of a material additive to such running surface and method of manufacture of such running surface

摘要

The invention concerns an improvement of gliding properties of running surfaces for winter sports apparatus, e.g. skis and snowboards. A running surface according to the invention contains a mineral addition chosen from the sodalite group and tsaregorodtsevite-wadalite series or a mixture thereof; especially preferred is an ultramarine as such mineral additive. Gliding properties are similar or improved in comparison to those obtainable with the addition of soot, carbon black or graphite. The mineral addition according to the invention can however be combined with the addition of soot, carbon black or graphite. The invention also opens up new possibilities in the coloration of running surfaces.
