How does the thermal conductivity of polyethylene compare to polypropylene in outdoor tables?

When selecting materials for outdoor tables, understanding thermal conductivity is crucial for durability and comfort. Polyethylene and polypropylene are two common plastics used in outdoor furniture, each with distinct thermal properties. Polyethylene has a lower thermal conductivity compared to polypropylene, meaning it retains heat less effectively and stays cooler to the touch in direct sunlight. This makes polyethylene a better choice for outdoor tables in hot climates, as it reduces the risk of discomfort from heat absorption. On the other hand, polypropylene, with slightly higher thermal conductivity, may feel warmer but offers greater rigidity and resistance to wear. Ultimately, the choice between polyethylene and polypropylene depends on the specific needs of the outdoor environment and user preferences.
