What are the differences in thermal expansion between PVC and polypropylene outdoor ottomans?
When selecting outdoor ottomans, understanding the thermal expansion properties of materials like PVC and polypropylene is crucial for long-term durability. PVC (polyvinyl chloride) exhibits higher thermal expansion compared to polypropylene, meaning it expands and contracts more significantly with temperature fluctuations. This can lead to warping or cracking over time, especially in extreme weather conditions. Polypropylene, on the other hand, has lower thermal expansion, making it more stable and resistant to temperature-induced deformation. For outdoor use, polypropylene ottomans are often the better choice due to their superior resistance to heat and cold. Consider these differences to ensure your outdoor furniture remains functional and aesthetically pleasing for years.
