How does prolonged exposure to ozone affect the durability of polypropylene outdoor ottomans?
Prolonged exposure to ozone can significantly reduce the durability of polypropylene outdoor ottomans. Ozone, a reactive gas, accelerates the oxidation process in plastics, leading to surface cracks, brittleness, and color fading. Polypropylene, while UV-resistant, is vulnerable to ozone-induced degradation over time, especially in high-pollution areas.
Signs of ozone damage include:
- Surface micro-cracks
- Loss of flexibility
- Chalky or discolored patches
To extend lifespan, consider:
- Using protective covers
- Applying UV-resistant coatings
- Storing ottomans indoors during extreme weather
Regular maintenance and material selection (e.g., ozone-stabilized polypropylene) can mitigate these effects, preserving both functionality and aesthetics.
