The role of PVC conveyor belt in underground coal mines is very important, because there are many risks of fire and explosion in the coal mine environment, and PVC conveyor belt can effectively reduce these risks. The belt body of PVC conveyor belt adopts high-strength, low-extension, high-quality polyester filaments in the longitudinal direction, and nylon filaments with high-strength and moderate modulus in the transverse direction. It has excellent flame-retardant and electrostatic conductivity. It also has the advantages of high strength, small elongation, light belt body, non-delamination of the belt body, impact resistance, tear resistance, and good groove formation of the belt body.
