How do synthetic rattan outdoor planters handle thermal expansion in sunlight?

Synthetic rattan outdoor planters are designed to withstand temperature fluctuations, including thermal expansion caused by sunlight exposure. The material, typically made from high-density polyethylene (HDPE) or resin, has inherent flexibility that allows it to expand and contract without cracking or warping. Manufacturers often incorporate UV stabilizers to prevent degradation from prolonged sun exposure, ensuring the planters retain their shape and color over time. Additionally, the woven or molded structure of synthetic rattan provides slight gaps or elasticity, accommodating minor dimensional changes due to heat. This makes them a durable and low-maintenance choice for outdoor spaces, even in varying weather conditions. For optimal performance, it's recommended to place them in partially shaded areas or use lighter colors to minimize heat absorption.
