Are polyethylene sculptures more prone to thermal expansion than PVC ones?
When comparing polyethylene and PVC sculptures, thermal expansion is a critical factor to consider. Polyethylene, a thermoplastic polymer, has a higher coefficient of thermal expansion than PVC, making it more susceptible to dimensional changes with temperature fluctuations. This property can affect the durability and stability of outdoor sculptures, especially in environments with extreme temperature variations. PVC, on the other hand, exhibits lower thermal expansion, offering better resistance to warping or cracking over time. Artists and designers must weigh these material characteristics when selecting the right medium for their projects, balancing aesthetics with practical performance. Understanding these differences ensures long-lasting and resilient artwork.
