common conveyor belts

relatively small deformation under high temperature condition.

Cotton conveyor belt 

1) Cotton canvas is woven by cotton fiber both in warp and in weft. Its elongation is relatively low; it is good in mechanical fastening and adhesion with rubber. Cotton conveyor belt has relatively small deformation under high temperature condition, suitable for short-distance and light-load transportation of materials.

2) Polyester cotton conveyor belt is the upgraded product of cotton conveyor belts, and its tension resistant body is woven by polyester cotton fibers in warp and cotton fibers in weft. Its comprehensive physical and mechanical characteristics are obviously better than those of cotton conveyor belt, especially the belt body is thinner and lighter, the belt has better shock resistance and thus it has better performance and can reduce energy and material consumption for users. It is the idea selection for medium, short-distance and medium-load transportation of materials.
