What chemical treatments are applied to PVC to prevent degradation in outdoor ottomans?

PVC (Polyvinyl Chloride) is a popular material for outdoor ottomans due to its durability and weather resistance. However, prolonged exposure to sunlight, heat, and moisture can cause degradation over time. To combat this, several chemical treatments are applied to PVC outdoor ottomans:

1. UV Stabilizers: These additives absorb or block harmful ultraviolet (UV) rays, preventing discoloration and brittleness caused by sun exposure.

2. Heat Stabilizers: These compounds protect PVC from thermal degradation during manufacturing and outdoor use, ensuring structural integrity.

3. Plasticizers: Added to enhance flexibility, plasticizers prevent cracking in cold temperatures and maintain the ottoman's shape.

4. Antioxidants: These chemicals slow down oxidation, which can weaken PVC over time.

5. Fungicides and Biocides: Used to prevent mold and mildew growth in humid conditions.

By incorporating these treatments, manufacturers ensure that PVC outdoor ottomans remain resilient and aesthetically pleasing for years, even in harsh weather conditions.
