How does resin brittleness at low temperatures affect WPC armchair durability?

Resin brittleness at low temperatures significantly affects the durability of Wood-Plastic Composite (WPC) armchairs. WPC materials, which combine wood fibers and plastic resins, are popular for outdoor furniture due to their weather resistance. However, when temperatures drop, the plastic resin component becomes more brittle, reducing the material's flexibility and increasing the risk of cracks or fractures under stress.

This brittleness can lead to structural weaknesses in WPC armchairs, especially in joints or load-bearing areas. Repeated exposure to freezing conditions may accelerate wear, shortening the product's lifespan. To mitigate this, manufacturers often modify resin formulations or add impact-resistant additives. Understanding this relationship helps consumers make informed choices for cold-climate outdoor furniture.
