PVC flame-retardant conveyor belts are primarily used in underground coal mines.

PVC flame-retardant conveyor belts are suitable for conveying materials under dry conditions with an inclination angle of 16 degrees or less. PVG flame-retardant conveyor belts are designed for conveying moist, waterlogged materials with an inclination angle of 20 degrees or less. The PVC flame-retardant belts are made by using an integral belt core as the skeletal material, which is then plasticized after being soaked and coated with flame-retardant and antistatic PVC materials. The flame-retardant conveyor belts, based on the belt's tensile strength and core structure, are connected using mechanical lugs, with the joint strength reaching 50%-90% of the belt's rated tensile strength; using vulcanized joints, the joint strength can reach 60%-90% of the belt's rated tensile strength. Various jointing methods can meet the diverse needs of customers, ensuring the safe and efficient operation of the system.
