Polyester(EP) Conveyor Belt
Polyester conveyor belt, also called EP conveyor belt, whose tension resistant body is canvas woven by polyester in warp and nylon in weft. (the longitudinal is EP, the transverse is NN) . The belts have the characteristics of low elongation in warp and good trough ability in weft, good water resistance, wet strength. The modulus of belt is high and elongation in service is small. The belt also has good heat stability and shock resistant. In that case the EP belt is suitable for middle and long distance, high load and high speed of conveying process.
