Polyester conveyor belt refers to the conveyor belt with EP polyester canvas as the skeleton. Its structure is single or multi-layer polyester canvas, and rubber covering layer and core rubber are combined into one through vulcanization process. In the case of super width or large carrying capacity and high speed, one or two layers of steel mesh tear prevention layer can be added to increase the transverse tensile strength of the conveyor belt, which can effectively avoid longitudinal tearing of the conveyor belt.
