How does the resistance to fading from industrial emissions vary among plastics?
The resistance to fading caused by industrial emissions varies significantly among plastics due to differences in their chemical composition and UV stability. Polycarbonate and acrylic plastics generally exhibit high resistance to fading, as their molecular structures are less prone to degradation from pollutants and UV exposure. In contrast, polyethylene and PVC are more susceptible to discoloration and weakening when exposed to industrial emissions over time. Additives like UV stabilizers can enhance fading resistance, but inherently stable polymers like PTFE (Teflon) perform best in harsh environments. For long-term durability in polluted areas, selecting plastics with high UV stability and chemical resistance is critical.
