What are the differences in thermal conductivity between WPC and rubber outdoor tree boxes?

When comparing the thermal conductivity of Wood-Plastic Composite (WPC) and rubber outdoor tree boxes, several key differences emerge. WPC, a blend of wood fibers and plastic, typically has lower thermal conductivity compared to rubber. This means WPC tree boxes tend to insulate better, reducing heat transfer and protecting tree roots from extreme temperature fluctuations.

Rubber, on the other hand, generally has higher thermal conductivity, allowing it to absorb and release heat more quickly. While this can be beneficial in some climates, it may lead to less stable root temperatures in harsh weather conditions.

For outdoor applications, WPC's lower thermal conductivity makes it a preferred choice for maintaining consistent soil temperatures, while rubber may require additional insulation in extreme environments. Understanding these differences helps in selecting the right material for your landscaping needs.
