What are the differences in resistance to organic solvents between polypropylene and PVC outdoor ottomans?

When selecting outdoor ottomans, understanding material durability is crucial, especially regarding resistance to organic solvents. Polypropylene and PVC are two common plastics used in outdoor furniture, but they differ significantly in their ability to withstand chemical exposure.

Polypropylene exhibits excellent resistance to most organic solvents, including alcohols, acids, and bases, making it a durable choice for outdoor use. Its semi-crystalline structure provides inherent stability against degradation. PVC, while resistant to water and some chemicals, is more susceptible to damage from ketones, esters, and aromatic hydrocarbons. Over time, PVC may soften or discolor when exposed to certain solvents.

For long-term outdoor use, polypropylene is often the superior option due to its broader solvent resistance and UV stability. However, PVC can be a cost-effective alternative in environments with minimal chemical exposure. Consider your specific needs and environmental factors when choosing between these materials for your outdoor ottoman.
