Nylon conveying belt
Common polyester conveyor belt is also named as EP conveyor belt, and has the features of warp low elongation and excellent weft trough formation property as its tensile body is canvas interwoven by warp terylene and weft polyamide, good water resistance, unchanged wet strength, no mildew, and lower safety factor as the initial modulus of polyester is high, and is suitable for conveying materials in medium and long distance and high transmission capacity at a high speed.
