Polyester conveyor belt



Polyester conveyor belt, also known as EP conveyor belt, its tensile body by polyester, weft is interwoven nylon canvas base performance characteristics into the groove when low elongation and excellent knot zonal performance, watergood wet strength does not drop, no mildew, high initial modulus of polyester, desirable lower safety factor, suitable for long distance high load transportation of materials under high-speed conditions. Second: It is widely used in the field of mines, docks, ports, electricity, building materials, coal, food, metallurgy, cement, foundry, chemical and transportation of materials. : Abrasion resistance, heat resistance, cold resistance, chemical corrosion, fire-retardant, antistatic type.
