Is polyethylene suitable for outdoor use without treatment?

Polyethylene is a widely used plastic known for its versatility and durability. However, when it comes to outdoor use without treatment, its suitability depends on several factors. Untreated polyethylene is generally resistant to moisture and chemicals, making it a good choice for short-term outdoor applications. However, prolonged exposure to UV radiation can cause degradation, leading to brittleness and discoloration over time. To enhance its outdoor durability, polyethylene is often treated with UV stabilizers or additives that improve its resistance to sunlight and weathering. For long-term outdoor use, treated polyethylene is recommended to ensure it maintains its structural integrity and appearance. In summary, while untreated polyethylene can be used outdoors temporarily, treated polyethylene is the better option for extended exposure to the elements.
