What is Polypropylene Density? | The Ultimate Guide for Artificial Plants

PP (polypropylene) density ranges 0.91±0.05 g/cm³, making it ideal for lightweight yet realistic artificial succulents.

Below I show our lab test result, pp material density in g cm3.

Why test density for fake plants?

Density affects product weight, material costs, and compatibility with mounting materials (e.g., foam, soil).

Does recycled PP have different density?

Yes, impurities may increase density by 0.02–0.05 g/cm³.

Does PP a good material for fake flower?

Yes,PP is good material for fake flower in good of lightweight,shape of strength,color fastness.
