Polyester Conveyor Belt

Quantity Order:

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