Polyurethane is a new type of polymer composite material and belongs to high-tech products,its nature between plastic and rubber but its performance is much better than the two, is an ideal material to replace them.
1. Long service time. Its service life is more than 8 times longer than the ordinary metal products and 3.9 times longer than the rubber products.
2. Large bear capacity. With good resilence, high strength to absorb the impact, high wear resistance, high tensile strength,so its capacity is more than 2.5 times stronger than the rubber and stainless products.
3. High sieving efficiency. On the base of meeting the size distribution, the mesh slot is made into the shape of rectangle. Which gurantees the ratio of qualified fine material and improves the screening effciency.
4. No blocking by the hole.With the resilience nature, the aperture is prevented from blockage.
5. Polyurethane sieve machine can reduce noise 5-20 decibels than metal mesh.
6. Abrasive resistant. Tear resistant and corrosive resistant.
