Steel Cord Flame Retardant Conveyor Belt for Coal Mines

Steel cord flame-retardant conveyor belts for coal mines boast high tensile strength and low elongation same as conventional steel cord conveyor belts, and additionally feature flame retardant and antistatic properties. They are particularly suitable for applications requiring flame resistance and explosion protection, such as underground coal mines.
