How does the resistance to acid rain vary among plastic outdoor armchair types?

Plastic outdoor armchairs are popular for their affordability and low maintenance, but their resistance to acid rain varies significantly depending on the type of plastic used. Here’s a breakdown of how different materials perform:

1. Polyethylene (PE): Highly resistant to acid rain due to its non-reactive nature. PE chairs are durable and often used in harsh weather conditions.

2. Polypropylene (PP): Offers good resistance but may degrade over prolonged exposure to acidic environments. Ideal for moderate climates.

3. Polyvinyl Chloride (PVC): While sturdy, PVC can become brittle when exposed to acid rain over time. Regular maintenance is recommended.

4. Recycled Plastics: Performance varies based on composition. Some recycled blends may lack consistent acid rain resistance.

For long-term durability, polyethylene and high-quality polypropylene are the best choices. Regular cleaning and protective coatings can also extend the lifespan of plastic outdoor armchairs in acidic conditions.
