Are PVC animal sculptures heavier than similar-sized polypropylene ones?

When choosing materials for animal sculptures, weight is often a key consideration. PVC (polyvinyl chloride) and polypropylene are both popular choices, but how do they compare in terms of weight? Generally, PVC animal sculptures tend to be heavier than similar-sized polypropylene ones due to the material's higher density.

PVC is a durable, rigid plastic with a density of around 1.3-1.45 g/cm³, making it heavier than polypropylene, which has a density of approximately 0.9-0.91 g/cm³. This difference means that a PVC sculpture of the same dimensions will weigh more, which may affect installation and transportation.

However, polypropylene offers advantages like flexibility and resistance to fatigue, making it ideal for lightweight, portable sculptures. Both materials are weather-resistant, but PVC is often preferred for outdoor use due to its sturdiness.

In summary, if weight is a concern, polypropylene may be the better option. For heavier, more robust sculptures, PVC is the go-to choice. Consider your project's needs when selecting between these two versatile materials.
