What temperature thresholds cause PVC bar stools to become brittle?

PVC bar stools are popular for their durability and affordability, but they can become brittle under certain temperature conditions. Generally, PVC starts to lose its flexibility and becomes brittle when exposed to temperatures below -10°C (14°F). At extremely low temperatures, the material's molecular structure hardens, increasing the risk of cracking or breaking under pressure.

On the other hand, prolonged exposure to high temperatures above 60°C (140°F) can also weaken PVC, making it more prone to brittleness over time. UV radiation from sunlight can accelerate this process, especially in outdoor settings.

To extend the lifespan of PVC bar stools, avoid exposing them to extreme cold or heat. For outdoor use, consider UV-resistant coatings or storing them indoors during harsh weather. Regular maintenance and proper care can help maintain their flexibility and durability for years.
