Polyester conveyor belt, also called EP or PN conveyor belt, whose tension resistant body is canvas, is woven by polyester in warp and polyamide in weft.

The belt has the characteristics of low elongation in warp and good trough ability in weft, good for water resistance and wet strength, suitable for medium, long distance and heavy-load transportation of materials.

Because of high initial modulus of polyester, the belts can choose a relative low safety factor.
