What are the effects of infrared radiation on PVC outdoor flower pot materials?

Infrared radiation can significantly impact PVC outdoor flower pot materials, leading to gradual degradation over time. Prolonged exposure to infrared rays, often accompanied by UV radiation, causes the plasticizers in PVC to break down, resulting in brittleness and reduced flexibility. Additionally, infrared heat accelerates color fading, making the pots appear dull and weathered. High temperatures from infrared exposure may also warp or deform thin-walled PVC pots. To mitigate these effects, manufacturers often add UV stabilizers and heat-resistant additives to improve durability. Choosing thicker, high-quality PVC pots or those with protective coatings can extend their lifespan in sunny outdoor environments. Regular maintenance, such as cleaning and occasional shading, further helps preserve the material's integrity.
