What is WPC（Wood-Plastic Composites）

The mixture is then processed via plastic-forming techniques such as extrusion, compression molding, or injection molding to create boards or profiles. WPC is primarily used in construction, furniture, logistics packaging, and other industries. Specifically, boards formed by hot-extruding a mixture of plastics and wood flour in specific proportions are termed "extruded wood-plastic composite boards."

WPC is properties are derived from its base materials: high-density polyethylene (HDPE) or polypropylene, combined with wood fibers, endowing it with a blend of plastic and wood characteristics:

Excellent Processability​
WPC retains wood-like workability—sawing, nailing, and planing can be performed with standard woodworking tools. Its nail-holding strength surpasses other synthetic materials, exceeding that of natural wood by 3 times and particleboard by 5 times. Its mechanical properties also outperform wood.

Superior Strength​
The plastic component provides WPC with good elastic modulus. Combined with reinforced fibers, it achieves mechanical properties (e.g., compressive strength, flexural resistance) comparable to hardwood. Its surface hardness is 2–5 times that of natural wood.

Water Resistance, Corrosion Resistance, and Long Lifespan​
Unlike wood, WPC resists strong acids/bases, water, and corrosion; it does not breed bacteria, resist termites, or mold. Its lifespan exceeds 50 years.

Adjustable Properties​
Additives enable polymerization, foaming, curing, or modification of plastics, allowing customization of WPC’s density, strength, and special features (e.g., anti-aging, anti-static, flame-retardant).

UV Stability and Colorability​
WPC exhibits good ultraviolet (UV) light stability and color retention.

Environmental Sustainability​
A major advantage is its ability to convert waste (e.g., plant fibers, recycled plastics) into valuable products. WPC is fully recyclable, decomposes safely, and avoids "white pollution," making it an eco-friendly material.

​Diverse Raw Materials

Plastic components primarily include HDPE or PP, while wood fibers can be wood flour, rice hulls, or wood fiber. Small amounts of additives and processing aids are also used.

​Design Flexibility​
WPC can be molded into arbitrary shapes and sizes to meet specific needs.
