How does resin thermal degradation during processing affect WPC armchair quality?

Resin thermal degradation during processing significantly impacts the quality of Wood-Plastic Composite (WPC) armchairs. When exposed to high temperatures, the polymer resin in WPC can break down, leading to weakened structural integrity, reduced durability, and surface defects such as discoloration or warping. This degradation occurs due to excessive heat or prolonged processing times, causing chain scission in the polymer matrix. As a result, the armchair may exhibit poor mechanical performance, including lower load-bearing capacity and increased brittleness. To mitigate these issues, manufacturers must optimize processing parameters like temperature, screw speed, and residence time to preserve resin stability and ensure high-quality WPC furniture. Proper additives, such as stabilizers, can also help minimize thermal degradation effects.
