A conveyor belt is disclosed having a reinforcement layer (6), a load-bearing cover layer (4) above the reinforcement layer (6), and a pulley cover layer (8) disposed below the reinforcement layer (6), where the load-bearing cover layer (4) comprises at least one hydrogenated nitrile rubber (HNBR) material. The one or more HNBR materials may have a hydrogenation percentage of from about 90% to about 96%, from about 92% to about 95%, or even about 94%. The load-bearing cover layer may be from about 4 mm to about 6 mm thick, or even from about 4 mm to about 5 mm thick. In some cases, the reinforcement layer includes a rubber matrix that may be formed from a nitrile rubber (NBR) or a mixture of a nitrile rubber (NBR) and natural rubber blended in an NBR: NR weight ratio of from 3: 1 to 9: 1. In some aspects, the reinforcement layer includes a plurality of reinforcement plies embedded in a rubber matrix. 披露了传送带，其具有加强层(6)、在加强层(6)上方的承载覆盖层(4)、以及设置在加强层(6)下方的皮带轮覆盖层(8)，其中承载覆盖层(4)包含至少一种氢化丁腈橡胶(HNBR)材料。该一种或多种HNBR材料可以具有从约9
