What are the most common issues with brittleness in aged plastic landscape tables?
Aged plastic landscape tables often suffer from brittleness due to several factors. One primary cause is prolonged exposure to UV radiation, which breaks down polymer chains, weakening the material over time. Temperature fluctuations also contribute, as repeated expansion and contraction stress the plastic, leading to micro-cracks. Additionally, low-quality plastics or those without UV stabilizers degrade faster, becoming brittle within a few seasons. Moisture absorption and chemical exposure (e.g., cleaning agents) can further accelerate deterioration. To prolong lifespan, choose high-density polyethylene (HDPE) or polypropylene tables with UV inhibitors and store them indoors during harsh weather. Regular maintenance, like applying protective coatings, can also help mitigate brittleness.
