How does the durability of polyethylene compare to polypropylene for outdoor furniture?

When choosing materials for outdoor furniture, durability is a key factor. Polyethylene and polypropylene are two popular options, but how do they compare in terms of longevity and performance? Polyethylene is known for its excellent resistance to moisture, UV rays, and chemicals, making it a strong contender for outdoor use. It is less prone to cracking and fading, even in harsh weather conditions. On the other hand, polypropylene is lightweight and resistant to impact, but it may degrade faster when exposed to prolonged sunlight and extreme temperatures. While both materials are durable, polyethylene often outperforms polypropylene in outdoor settings due to its superior weather resistance and ability to maintain structural integrity over time. For long-lasting outdoor furniture, polyethylene is generally the better choice.
