1, The tear strength is increased by at least 15%, and the service life of the lifting belt is prolonged.
2, The production efficiency can be increased by at least 20%. The manufacturing process is simple and the equipment investment cost is low.
3, The transverse rigidity is improved, the stability, tear resistance and the longitudinal flexibility is much better; the overall thickness is reduced, and the weight per unit area is light, which saves the cost.
