When selecting synthetic rattan for urban outdoor furniture, the choice often narrows down to two primary materials: polyethylene (PE) and polypropylene (PP). Understanding their differences is crucial for making a durable and cost-effective investment.
The most significant distinction lies in their composition and resulting durability. Polyethylene rattan is a premium option, renowned for its exceptional resistance to ultraviolet (UV) rays and extreme weather conditions. It is manufactured through an intricate process where color is integrated throughout the material, making it highly fade-resistant. This makes PE rattan ideal for furniture that will be permanently placed on sunny rooftops, balconies, or patios, as it can withstand prolonged sun exposure without becoming brittle or losing its vibrant color.
Polypropylene rattan, on the other hand, is a more economical choice. While it is UV-stabilized, it is generally less resistant to intense, direct sunlight over many years compared to PE. The color in PP rattan is often applied as a surface coating, which can make it more susceptible to fading over time. However, polypropylene is highly resistant to moisture and chemicals, making it easy to clean and suitable for areas with high humidity.
In terms of feel and aesthetics, polyethylene strands are typically thicker and softer, closely mimicking the look and texture of natural rattan. Polypropylene strands can be thinner and have a slightly more plastic-like appearance, though high-quality versions are very convincing.
Maintenance for both materials is straightforward, usually requiring just a wipe-down with soapy water. The key difference emerges in longevity. High-density polyethylene (HDPE) furniture can last 10-15 years or more with minimal degradation, while polypropylene furniture may have a shorter lifespan, especially in harsh, sun-drenched environments.
Ultimately, your choice depends on your specific needs. For permanent urban outdoor settings where maximum durability and fade resistance are priorities, polyethylene is the superior, though more expensive, option. For budget-conscious projects or furniture that may be used in shaded areas or seasonally stored, polypropylene offers excellent value.
