Are polyethylene sculptures heavier than PVC counterparts of the same size?
When comparing polyethylene and PVC sculptures of the same size, the weight difference primarily depends on the materials' densities. Polyethylene has a density ranging from 0.91 to 0.96 g/cm³, while PVC is denser, typically around 1.3 to 1.45 g/cm³. This means PVC sculptures are generally heavier than polyethylene ones of identical dimensions. However, factors like additives, fillers, or structural design can slightly alter the weight. For artists and buyers, understanding these differences helps in selecting the right material based on durability, cost, and intended use. Always consider the specific type of polyethylene or PVC, as variations exist within each material category.
