What are the differences in thermal stability between PVC and polyethylene tables?

When comparing the thermal stability of PVC (Polyvinyl Chloride) and polyethylene tables, several key differences emerge. PVC generally exhibits higher thermal stability, with a melting point around 160-210°C (320-410°F), while polyethylene melts at a lower range of 105-135°C (221-275°F). This makes PVC more suitable for applications requiring higher heat resistance, such as outdoor furniture exposed to direct sunlight.

Polyethylene, particularly HDPE (High-Density Polyethylene), is less heat-resistant but offers better flexibility and impact resistance at lower temperatures. PVC tables may deform or release harmful chlorine gases when overheated, whereas polyethylene tends to soften without emitting toxic fumes. For environments with moderate temperatures, polyethylene tables are often preferred due to their durability and safety.

In summary, PVC tables outperform polyethylene in high-heat scenarios, but polyethylene is a safer and more versatile choice for everyday use. Consider your specific needs when selecting between these materials.
