What are the effects of prolonged exposure to high-altitude UV radiation on polyethylene outdoor chairs?
Prolonged exposure to high-altitude UV radiation significantly impacts polyethylene outdoor chairs, causing UV degradation over time. At higher elevations, UV intensity increases, accelerating the breakdown of polyethylene molecules. This leads to discoloration, surface cracking, and loss of structural integrity. The chairs may become brittle, reducing their lifespan and safety. UV stabilizers in manufacturing can mitigate these effects, but unprotected polyethylene will eventually deteriorate. Regular maintenance, such as applying UV-protective coatings or storing chairs during peak sunlight hours, can help prolong their usability. Understanding these effects is crucial for selecting durable outdoor furniture for high-altitude environments.
