How does resin compatibilizer content affect wood-plastic interface strength in flower boxes?
The performance of wood-plastic composites (WPCs) in flower boxes heavily depends on the interfacial strength between wood fibers and the plastic matrix. Resin compatibilizers play a crucial role in improving this bond by enhancing adhesion and reducing phase separation. Studies show that increasing compatibilizer content up to an optimal level (typically 3-5%) significantly boosts tensile and flexural strength, while excessive amounts may lead to brittleness. Properly balanced compatibilizer content ensures better moisture resistance and longevity, making flower boxes more durable for outdoor applications. Manufacturers must carefully calibrate this additive to achieve the ideal balance between mechanical properties and cost-effectiveness.
