What are the effects of prolonged ozone exposure on WPC materials?
Prolonged ozone exposure can significantly impact the performance and durability of Wood-Plastic Composite (WPC) materials. Ozone, a reactive gas, causes oxidative degradation in WPCs, leading to surface cracks, discoloration, and reduced mechanical strength. Over time, this degradation weakens the material's structural integrity, making it more prone to breakage and wear. Additionally, prolonged exposure may alter the aesthetic appeal of WPCs, affecting their suitability for outdoor applications. Manufacturers often incorporate stabilizers to mitigate these effects, but long-term ozone resistance remains a challenge. Understanding these impacts helps in selecting the right WPC materials for environments with high ozone concentrations.
