Abstract:
1. A power-transmission belt or transport belt with a belt base or a cord-embedment zone made of a synthetic elastomer and with, embedded into the synthetic elastomer, at least one tension-member system made of a cord, wherein the cord is comprised of strands which define an interstice volume therebetween and a fill material, wherein at least a portion of the fill material is positioned in the intersice volume between the strands, and wherein the fill material differs from the synthetic elastomer, wherein the cord of the at least one tension-member system includes less than 0.20 mg of the synthetic elastomer of the belt base or cord embedment zone per mm 3 of cord volume and wherein the fill material present in the cord is selected from the group consisting 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.
