Abstract (en)
[origin: US4705815A] An antibackslide treatment for a cross-country ski consists of a polyurethane containing a filler or closed-pore structure and which combined hydrophobicity with an elastic character which varies depending upon the velocity of its deformation. During the propulsion phase where the velocity of deformation is low, the treatment has viscoelastic characteristics whereas during the sliding phase when the velocity of deformation is high, the treatment has more elastic properties.
