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 troughability 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.
