What are the effects of prolonged exposure to diesel exhaust on WPC?

Prolonged exposure to diesel exhaust can significantly degrade wood-plastic composites (WPC), leading to reduced durability and structural integrity. Diesel emissions contain harmful pollutants like nitrogen oxides and particulate matter, which accelerate material breakdown. Over time, WPC may experience discoloration, surface cracking, and loss of mechanical strength. This degradation is particularly concerning in urban or industrial settings where WPC is used in construction or outdoor applications. Preventive measures, such as protective coatings or improved material formulations, can help mitigate these effects. Understanding the risks ensures better material selection and maintenance for long-term performance.
