1. Long service life and large load-bearing capacity. Since the polyurethane elastic screen plate uses steel wire rope as the skeleton material, and polyurethane itself has a very high elastic modulus, high-strength impact absorption and high wear resistance, it has a very high tensile strength, and its load-bearing capacity is more than 2.5 times that of the rubber screen plate. Its service life is 8-10 times higher than that of ordinary metal screen plates, 3 times that of stainless steel screen surfaces, and 3.9 times that of natural rubber. It is the screen surface material with the best wear resistance in the world. The production material of polyurethane screen plates is a high-molecular organic elastomer, which has wear resistance, flexibility resistance, and large load-bearing capacity. The raw materials for the production of polyurethane screen plates have been specially treated to ensure that they will never delaminate under long-term alternating loads.
2. High screening efficiency. The screen surface has self-cleaning properties, does not block holes, and has high screening efficiency. Because polyurethane has strong water permeability and a large cone angle of the screen hole (140°), it can effectively prevent the adhesion of wet fine particles, so it is suitable for screening and grading of wet fine particles. The polyurethane screen plates of our factory are made of imported raw materials. Their elastomers and good relaxation properties can effectively avoid blockage under dynamic conditions.
3. Wide application range, stronger professional applicability, suitable for any type of vibrating screen machine and can be made by measuring machine. Polyurethane screen plates are professionally used in hydropower stations, building materials and other metal beneficiation industries. Screening of various materials in the range of 0.1mm-170mm, whether dry screening or wet screening, does not affect the screening efficiency. For dehydration and de-mediation screening in the range of 0.5m-3mm, the superiority of polyurethane screen surface is more fully demonstrated. The product is water-resistant, corrosion-resistant, aging-resistant, and easy to replace and maintain. Polyurethane has a low density (1.32kg/m3) and is lighter than metal screen surfaces, which can reduce production unit consumption, so it can adapt to the requirements of large-scale development of screen machines.
4. High screening accuracy. The production process of polyurethane screen plates adopts mold casting molding process, with accurate aperture and high screening quality. The particle size of the material under the screen can well meet the requirements of users. The product is easy to install and replace and repair. It is suitable for any type of screening machine. It is light in weight and can be installed on site or replaced and repaired, which greatly reduces the workload.

5. Low working noise, in line with national environmental noise standards. According to actual measurements, the same screening machine using polyurethane screen plates can reduce noise by 5-20 decibels compared to metal screen plates, and greatly reduce dust flying, so that the production site has a quiet and clean working environment.
6. Significant economic benefits. Although the price of polyurethane rubber screen surface is higher than that of metal screen plates, if the screening efficiency, maintenance costs, service life and other factors are considered comprehensively, it will be found that the overall benefits of polyurethane screen surface are much better than ordinary metal screen surface. According to the survey, every ton of polyurethane rubber screen plate can save 45 tons of steel. The maintenance cost is saved by more than 40,000 yuan. Therefore, polyurethane screen surface will replace steel screen surface. It will be the inevitable choice for most companies in the future.
