Is PVC naturally resistant to UV damage?

PVC, or polyvinyl chloride, is a widely used synthetic plastic polymer known for its durability and versatility. However, when it comes to UV resistance, PVC does not naturally withstand prolonged exposure to ultraviolet rays. Without proper additives or treatments, PVC can degrade over time when exposed to sunlight, leading to discoloration, brittleness, and reduced structural integrity.

To enhance its UV resistance, manufacturers often incorporate stabilizers and UV inhibitors during the production process. These additives help protect PVC from the harmful effects of UV radiation, making it suitable for outdoor applications such as piping, window frames, and roofing materials.

In summary, while PVC is not inherently resistant to UV damage, it can be engineered to withstand sunlight exposure effectively. For long-term outdoor use, it is crucial to select UV-stabilized PVC products to ensure durability and performance.
