Polyester Conveyor Belt
Products properities:
A- Polyester conveyor belt, also called EP or PN conveyor belt, whose tension resistant body is canvas woven by polyester in warp and polyamide in weft.
B- The belt has the characteristics of low elongation in warp and good trough ability in weft, good water resistance, good wet strength, suitable for medium, long distance and heavy-load transportation of materials.
C- Because of the high initial modulus of polyester, the belts can choose a relative low safety factor.
