Are polypropylene sculptures more resistant to fading than PVC under UV light?
When choosing materials for outdoor sculptures, resistance to UV light is a critical factor. Polypropylene and PVC are both popular choices, but how do they compare in terms of fading resistance? Polypropylene is known for its durability and higher resistance to UV degradation, making it less prone to fading over time compared to PVC. PVC, while cost-effective and versatile, tends to degrade faster under prolonged UV exposure, leading to discoloration and brittleness. For long-lasting outdoor art, polypropylene may be the superior option due to its enhanced UV stability. However, proper coatings and treatments can improve PVC's performance. Ultimately, the choice depends on budget, aesthetic requirements, and expected lifespan.
