How does the resistance to hydrolysis differ between PVC and polyethylene outdoor armchairs?
When selecting outdoor armchairs, understanding the hydrolysis resistance of materials like PVC and polyethylene is crucial for long-term durability. PVC (polyvinyl chloride) exhibits moderate resistance to hydrolysis, making it suitable for damp environments but prone to degradation under prolonged UV exposure and extreme weather. Polyethylene, especially high-density polyethylene (HDPE), offers superior hydrolysis resistance due to its non-polar molecular structure, which repels water and resists chemical breakdown. While PVC may crack or weaken over time, polyethylene maintains its integrity, making it ideal for harsh outdoor conditions. For weather-resistant furniture, polyethylene often outperforms PVC in hydrolysis resistance and overall longevity.
