What are the differences in thermal expansion between natural and synthetic rattan outdoor armchairs?

When choosing rattan outdoor armchairs, understanding thermal expansion differences between natural and synthetic rattan is crucial for durability and comfort. Natural rattan, made from woven palm stems, expands and contracts more significantly with temperature changes. This can lead to loosening or warping over time, especially in extreme climates. Synthetic rattan, typically crafted from polyethylene or PVC, has superior resistance to thermal expansion, maintaining its shape and structural integrity in varying temperatures.

Natural rattan's organic fibers absorb moisture, exacerbating expansion in humid conditions, while synthetic rattan's plastic composition minimizes these effects. For outdoor use in regions with high temperature fluctuations, synthetic rattan is often the more stable choice. However, natural rattan offers a classic aesthetic and eco-friendly appeal, despite requiring more maintenance. Consider your local climate and desired upkeep when selecting between these materials for long-lasting outdoor furniture.
