How do polypropylene outdoor chairs resist discoloration from algae or lichen?
Polypropylene outdoor chairs are highly resistant to discoloration caused by algae or lichen due to their unique material properties. Polypropylene is a synthetic polymer that is inherently non-porous, preventing moisture absorption and inhibiting the growth of algae and lichen. Additionally, these chairs are often treated with UV stabilizers, which protect against sun damage and further reduce the likelihood of organic growth. The smooth surface of polypropylene also makes it difficult for spores to adhere, ensuring the chairs remain clean and vibrant over time. For added protection, many manufacturers incorporate antimicrobial additives during production, enhancing their resistance to discoloration and extending their lifespan in outdoor environments.
