Are polypropylene outdoor bar stools more heat-resistant than polyethylene versions?

When choosing outdoor bar stools, heat resistance is a key factor, especially in sunny or high-temperature environments. Polypropylene and polyethylene are two common materials used in outdoor furniture, but how do they compare in terms of heat resistance?

Polypropylene is known for its higher melting point (around 160°C or 320°F) compared to polyethylene (approximately 120°C or 248°F), making it more resistant to heat deformation. This means polypropylene bar stools are less likely to warp or soften under direct sunlight or warm conditions. Additionally, polypropylene is more rigid and retains its shape better over time.

Polyethylene, while durable and flexible, may become softer in extreme heat, potentially leading to sagging or distortion. However, it offers better impact resistance and is often more affordable.

For outdoor use in hot climates, polypropylene bar stools are generally the better choice for heat resistance. However, consider factors like UV stability, weight capacity, and overall design to ensure the best fit for your space.
