How does the resistance to warping of PVC compare to polyethylene in outdoor tables?

When selecting materials for outdoor tables, resistance to warping is a critical factor to consider. PVC (polyvinyl chloride) and polyethylene are two popular choices, each with distinct properties. PVC is known for its excellent dimensional stability and resistance to warping, even under prolonged exposure to sunlight and moisture. This makes it a reliable option for outdoor furniture that requires minimal maintenance.

On the other hand, polyethylene, while durable and resistant to impact, is more prone to warping over time, especially when exposed to extreme temperature fluctuations. This is because polyethylene has a lower rigidity compared to PVC, making it less stable under stress.

In summary, PVC outperforms polyethylene in terms of warping resistance for outdoor tables, offering greater durability and longevity in harsh weather conditions. If you prioritize a material that maintains its shape and structural integrity over time, PVC is the superior choice.
