Polyester Conveyor Belt
Polyester conveyor belts, also called EP conveyor belts, whose tension resistant body is canvas woven by polyester in warp and nylon-66 in weft. The belts have the characteristics of low elongation in warp and good trough ability in weft, good water resistance, good wet strength, no mould, suitable for medium, long-distance and heavy-load transportation of materials. Because of the high initial modulus of polyester, the belts can choose a relative low safety factor.
