Enhance the band (rubber to enhance the band) hanging from the multi-stack package made of plastic fabric, generally should be covered with a plastic outer core. Divided according to the different temperature zone and heat to enhance the general upgrading belt; with a core material according to the different divided into cotton, polyester cotton woven, nylon and EP raise with. According to enhance the performance characteristics with different upgrade can also be divided into heat with the general upgrading belt. Covered with rubber to enhance physical performance and level: according to the wear of materials to be transported into a strong load and wear (D type), moderate wear (L type) and transmission high-temperature heat-resistant materials (T-type). Enhance the band width of the specifications: the specifications have improved with the main 150 200 250 300 350 400 500 600mm, etc.
