In industrial production, screens are one of the key equipments, and their performance and life span directly affect production efficiency and costs. Polyurethane screens have become the first choice in many industries due to their excellent wear resistance and flex resistance. However, what factors affect its service life?

Factors affecting the life of polyurethane screen

1. Material characteristics: As a polymer organic elastomer, polyurethane has excellent wear resistance, flexibility resistance and load-bearing capacity. However, polyurethane screens produced by different manufacturers have differences in raw material ratios, production processes, etc. These differences directly affect the durability of the screens.

2. Usage environment: The service life of polyurethane screens is significantly affected by the use environment. Humid and high-pH environments will accelerate the aging process of polyurethane, resulting in reduced screen performance and shortened service life. Therefore, screens used in harsh environments need to be replaced more frequently.

3. Mechanical stress: During use, the screen will withstand mechanical stress such as extrusion and impact from the material. Screens that are subjected to high mechanical stress for a long time are prone to deformation, cracks or even fractures, thus affecting their service life. Therefore, reasonable control of the load and vibration frequency of the screen is the key to extending its life.

4. Contact between light and chemicals: Prolonged light exposure will cause the surface of the polyurethane screen to turn yellow and discolor, affecting its aesthetics and service life. Also, contact with certain chemicals can cause polyurethane to break down, shortening the life of the screen.

In summary, the service life of polyurethane screens is a complex and changeable issue, which is affected by multiple factors such as material characteristics, use environment, mechanical stress, exposure to light and chemicals, etc. In order to extend the service life of polyurethane screens, companies need to start from multiple aspects and adopt comprehensive management measures. Only in this way can we ensure that the screen plays its maximum role in the production process and create greater economic benefits for the enterprise.
