How does the weatherability of PVC compare to polyethylene in outdoor seating?

When choosing materials for outdoor seating, durability and weather resistance are critical factors. PVC (polyvinyl chloride) and polyethylene are two common plastics used in outdoor furniture, but their performance varies significantly under environmental stress.

PVC is known for its excellent UV resistance and structural stability, making it less prone to cracking or fading over time. However, it can become brittle in extreme cold and may degrade under prolonged exposure to high temperatures.

Polyethylene, particularly high-density polyethylene (HDPE), offers superior flexibility and impact resistance, performing well in both hot and cold climates. It resists moisture absorption and is less likely to warp or crack. However, it may fade faster under intense sunlight compared to PVC.

For long-term outdoor use, polyethylene often outperforms PVC in overall weatherability, especially in regions with fluctuating temperatures. PVC remains a strong choice for UV-heavy environments but requires additives to enhance its cold-weather performance. Your ideal choice depends on climate conditions and maintenance preferences.
