What are the thermal expansion rates of polypropylene vs. PVC loungers?
When selecting materials for outdoor loungers, understanding thermal expansion rates is crucial for durability and performance. Polypropylene has a thermal expansion coefficient of approximately 100-150 x 10^-6/°C, making it more prone to expansion under heat compared to PVC, which expands at about 50-80 x 10^-6/°C. This difference means polypropylene loungers may warp or deform more in high temperatures, while PVC retains better dimensional stability. For hot climates, PVC is often the preferred choice, whereas polypropylene offers flexibility and lightweight advantages in moderate conditions. Consider these factors to ensure long-lasting comfort and functionality in your outdoor furniture.
