A power-transmission or transport belt that includes a tension-member system made of a cord. The cord includes strands that define an interstice volume and a fill material. A portion of the fill material is positioned in the interstice volume between the strands. The fill material is one of: a) compounds derived from hydroxyaromatics with aldehydes, without addition of rubber or rubber latex, b) a non-rubber-containing post-curable hydroxyaromatic-aldehyde resin, and c) reaction products of hydroxyaromatics or hydroxyaromatic-aldehyde compounds with isocyanates or with isocyanate prepolymers. The belt makes it possible to adjust the fill material, such as when condensation levels of the hydroxyaromatics are low, in such a way that the fill material remains soft and elastic, thus giving optimized retention of the flexibility of the cord. |
