How does polypropylene compare to PVC in terms of longevity?

When comparing polypropylene and PVC in terms of longevity, several factors come into play. Polypropylene is known for its excellent chemical resistance, flexibility, and ability to withstand high temperatures, making it highly durable in harsh environments. It is less prone to cracking or degrading over time, even when exposed to UV light or extreme weather conditions.

On the other hand, PVC (polyvinyl chloride) is also a durable material, particularly valued for its strength and resistance to moisture and chemicals. However, PVC can become brittle over time when exposed to prolonged sunlight or extreme temperatures, which may reduce its lifespan in outdoor applications.

In summary, polypropylene generally offers superior longevity in environments with high UV exposure or temperature fluctuations, while PVC performs well in stable, indoor conditions. The choice between the two depends on the specific application and environmental factors.
