Polyester conveyor belts

Name: Polyester conveyor belts
Fabric specs : EP-80~EP+630
Width（mm）: 300~2600

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