What are the differences in thermal degradation between WPC and ABS plastic tree boxes?

When comparing the thermal degradation of Wood-Plastic Composite (WPC) and Acrylonitrile Butadiene Styrene (ABS) plastic tree boxes, several key differences emerge. WPC, a blend of wood fibers and thermoplastics, tends to degrade at lower temperatures compared to ABS due to the organic wood content. The lignin and cellulose in WPC begin to break down around 200°C, leading to charring and reduced mechanical strength.

In contrast, ABS, a synthetic polymer, exhibits higher thermal stability, with degradation typically starting above 400°C. ABS maintains its structural integrity longer under heat, making it more suitable for high-temperature environments. However, ABS releases toxic fumes like styrene and cyanide during degradation, while WPC produces less harmful byproducts.

Both materials have trade-offs: WPC is eco-friendlier but less heat-resistant, while ABS offers superior thermal performance but poses environmental and health risks. Understanding these differences helps in selecting the right material for specific applications.
