Why is polyurethane screen more and more accepted by users?

The rapid development of polyurethane screen is due to its excellent performance, such as high wear resistance, high mechanical strength, strong elasticity, slow aging, corrosion resistance and so on. These excellent properties are inseparable from the molecular structure of polyurethane materials: the main chain of polyurethane is composed of flexible long-chain polyols and rigid isocyanate blocks, which can effectively disperse the stress effect. The coexistence of polar and non-polar segments also improves the chemical stability of polyurethane. At the same time, the widespread hydrogen bonding in the polymer further improves the mechanical properties of the material Performance.
In addition, the NCO group of isocyanate is very active, which can react with alcohol, water and organic amine quickly, and the processing performance of the material is good. Through reaction conditions and catalyst control, various polyurethane products with different hardness and different structures can be obtained, such as elastomers like rubber or plastics, sponge with openings, rigid foam with closed cell structure, adhesives, coatings, sealants, etc., which are widely used in various fields of national life.
Polyurethane elastomer is a kind of material with both rubber and plastic properties. Its fate is determined by its good tensile strength, tear resistance, impact resistance, wear resistance, weather resistance, hydrolysis resistance and oil resistance. It is mainly used as structural materials (such as hose, gasket, tire, roller, gear, pipe, etc.), insulator, sole and solid tire. For example, as a mining sieve plate, compared with the traditional metal sieve plate, low noise, high permeability, wear resistance, etc.
The most important factor of screen or sieve plate is its long service life, and its wear resistance is directly related to its service life. Therefore, as an excellent wear-resistant material, it is more and more accepted and used by people.
