What are the UV degradation rates for different plastic composites in landscape tables?

Plastic composites are widely used in landscape tables due to their durability and low maintenance. However, prolonged exposure to UV radiation can degrade these materials, affecting their lifespan and performance. This article examines the UV degradation rates of common plastic composites, including polyethylene (PE), polypropylene (PP), and acrylonitrile butadiene styrene (ABS), in outdoor settings.

Studies show that polyethylene-based composites exhibit moderate UV resistance but may require stabilizers to prolong usability. Polypropylene, while cost-effective, degrades faster under UV exposure unless treated with additives. ABS demonstrates better UV stability but is prone to discoloration over time. Advanced composites like fiber-reinforced polymers (FRP) offer superior resistance but at a higher cost.

Factors such as pigment concentration, UV stabilizers, and geographic location significantly influence degradation rates. For instance, tables in high-sunlight regions may degrade 20-30% faster than those in temperate climates. Regular maintenance, such as applying UV-protective coatings, can mitigate these effects.

By understanding these degradation rates, manufacturers and consumers can make informed choices for long-lasting, sustainable outdoor furniture solutions.
