What are the effects of long-term moisture exposure on polyethylene outdoor chair joints?
Polyethylene outdoor chairs are popular for their durability and weather resistance, but prolonged moisture exposure can significantly impact their joints. Over time, moisture seeps into the material, causing swelling, weakening, and eventual cracking at joint connections. This degradation compromises structural integrity, leading to wobbling or breakage. UV radiation combined with moisture accelerates oxidative degradation, making joints brittle. Mold and mildew growth in damp conditions further deteriorates the material. To extend lifespan, choose UV-stabilized polyethylene and store chairs in dry conditions when not in use. Regular inspections and prompt repairs can also mitigate long-term damage.
