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

Thermal expansion is a critical factor to consider when choosing materials for outdoor furniture, particularly rattan. Natural rattan, derived from palm plants, exhibits minimal thermal expansion due to its organic composition and fibrous structure. In contrast, synthetic rattan, typically made from polyethylene or PVC, expands more significantly under heat because of its plastic-based properties.

Natural rattan's low thermal expansion makes it more stable in fluctuating temperatures, reducing the risk of warping or cracking. However, it requires regular maintenance to prevent moisture damage. Synthetic rattan, while more prone to expansion, offers superior resistance to weathering and UV rays, making it a popular choice for long-lasting outdoor furniture.

Understanding these differences helps consumers select the right material based on climate conditions and maintenance preferences. Natural rattan suits those prioritizing eco-friendliness, while synthetic rattan excels in durability and low upkeep.
