Are there compatibility issues between different resin types and wood fibers in WPC?
Wood-Plastic Composites (WPC) are widely used in construction and furniture due to their durability and sustainability. However, compatibility issues between resin types (such as PE, PP, or PVC) and wood fibers can affect performance. Factors like moisture absorption, thermal expansion, and adhesion strength play critical roles. For instance, hydrophobic resins may struggle to bond with hydrophilic wood fibers, leading to weak interfaces. Solutions include chemical treatments, coupling agents, or optimized processing techniques. Understanding these interactions ensures better WPC quality and longevity in applications.
