It has the characteristics of wear resistance, antistatic, waterproof, flame retardant, high strength, excellent safety performance, lower cost and lower price compared with other flame retardant conveyor belts. The whole core flame retardant conveyor belt can be divided into PVC type and PVG type. The top cover and bottom cover layers of PVC type are PVC cover rubber, with single side rubber ≥ 0.8mm. The top and bottom covering layers of PVG type are NBR and PVC, with single side thickness of 1.5mm-4.5mm. The transportation inclination of PVC type conveyor belt is less than 16 ° and that of PVG type conveyor belt is less than 20 ° which can be used for coal mine transportation.
