What are the differences in moisture retention between natural and synthetic rattan outdoor trash cans?

When selecting outdoor trash cans, understanding moisture retention differences between natural and synthetic rattan is crucial for durability and maintenance. Natural rattan, derived from palm plants, possesses organic fibers that readily absorb atmospheric moisture. This hydrophilic nature makes untreated natural rattan susceptible to swelling, mold growth, and structural weakening when exposed to rain or humidity. Without proper sealing treatments, natural rattan containers may develop cracks or rot over time.

Synthetic rattan, typically manufactured from polyethylene (PE) or polyvinyl chloride (PVC), features non-porous polymer structures that inherently resist water absorption. These manufactured fibers contain microscopic closed cells that prevent moisture penetration, allowing water to bead up and roll off surfaces. The synthetic material maintains dimensional stability in humid conditions and won't develop mildew or deteriorate from moisture exposure.

The key distinction lies in absorption rates: natural rattan can absorb up to 25% of its weight in moisture, while synthetic variants absorb less than 1%. This fundamental difference impacts cleaning requirements—synthetic rattan simply needs rinsing, while natural rattan may require thorough drying and protective coatings. For consistently humid or rainy environments, synthetic rattan offers superior moisture resistance, though both materials benefit from protective covers during extreme weather.
