The Best Replacement of Traditional Woven Belt Shengyuan high-speed needle punched corrugated cardboard conveyor belt/Overpass traction belt has advantages as below: A. High speed, high wear resistance(more than 350m/min) B. High belt surface flatness, good elasticity, is more beneficial to improve the quality of cardboard. C. Water absorption and dehumidification performance are better than the similar product in the current domestic and foreign markets. D. Normal service life is more than 40 million extension meters. E. There is no significant geometry change of the belt during the whole production process.

The sample is taken with a length of 20 mm and a width of 60 mm at a high temperature of 200 ºC with a tension of 0.72KN for 10 minutes to test the results. It is proved that the belt keeps the geometric dimension unchanged during normal operation.
