How does the color of polyethylene change over time in Outdoor Square Tables?
Polyethylene, a widely used material in outdoor furniture like square tables, undergoes noticeable color changes over time due to environmental factors. When exposed to prolonged sunlight, UV radiation breaks down the polymer chains in polyethylene, leading to a process called photodegradation. This results in the material losing its original vibrancy and developing a faded or chalky appearance. Additionally, temperature fluctuations, moisture, and pollution can accelerate this process. Manufacturers often add UV stabilizers and pigments to slow down color fading, but over years of outdoor use, even treated polyethylene will show signs of discoloration. Understanding these changes helps in selecting durable materials and maintaining the aesthetic appeal of outdoor furniture.
