The composition material of Polyurethane Screen is polymer organic elastomer, which has excellent wear resistance, flex resistance and large load-bearing capacity, and has been specially treated to ensure that it will never be delaminated under long-term alternating load. The bearing capacity of Polyurethane Screen is higher, which is more than 2.5 times that of rubber screen mesh, and its service life is 8-10 times longer than that of ordinary metal Polyurethane Screen, 3 times that of stainless steel Polyurethane Screen and 3.9 times that of natural rubber.
