How does the resistance to warping of polyethylene compare to polypropylene in outdoor tables?

When choosing materials for outdoor tables, understanding their resistance to warping is crucial. Polyethylene and polypropylene are two popular plastics used in outdoor furniture, but they differ significantly in performance. Polyethylene is known for its excellent resistance to warping, even under prolonged exposure to sunlight and moisture. Its molecular structure provides flexibility and durability, making it less prone to deformation over time. On the other hand, polypropylene, while lightweight and cost-effective, is more susceptible to warping when exposed to extreme weather conditions. This is due to its lower resistance to UV radiation and thermal expansion. For outdoor tables that require long-term durability and minimal maintenance, polyethylene is often the superior choice. However, polypropylene may still be suitable for less demanding environments or temporary setups. Ultimately, the decision depends on the specific requirements of the outdoor space and the desired lifespan of the furniture.
