What are the bending modulus properties of WPC in outdoor bin lids?

Wood-Plastic Composite (WPC) materials are widely used in outdoor bin lids due to their durability and resistance to environmental factors. The bending modulus, a key mechanical property, measures the material's stiffness under flexural loads. For WPC in outdoor bin lids, the bending modulus typically ranges from 1 to 4 GPa, depending on the composition of wood fibers and plastic polymers. This property ensures that the lids maintain structural integrity when subjected to weight, wind, or impact, preventing deformation or failure. Factors such as moisture exposure, UV radiation, and temperature fluctuations can influence the bending modulus over time, potentially reducing stiffness. Manufacturers often enhance this through additives or optimized processing to improve performance in harsh outdoor conditions, making WPC a reliable choice for long-lasting bin lids that combine strength with lightweight characteristics.
