The Types facet of Wood Biofiber Plastic Composite (WPC) market taxonomy classifies products by polymer matrix and fiber composition, influencing processing, cost, and end‑use suitability. Thermoplastic‑based WPC—primarily using polyethylene, polypropylene, or PVC—dominates due to its melt‑processability and recyclability, representing the bulk of the market. Thermoset‑based WPC, incorporating phenolic or epoxy resins, occupies a niche segment (approximately 10%) where higher temperature resistance and structural rigidity are required, such as in automotive interior panels. Within thermoplastics, further differentiation exists between high‑density polyethylene (HDPE) WPC and polypropylene (PP) WPC, each offering distinct tensile strength and moisture resistance profiles that affect application choice. Fiber sources also vary: wood flour is the most common, providing cost efficiency and familiar aesthetics, while agro‑fibers (e.g., bamboo, rice husk) are gaining traction for enhanced sustainability credentials. This typological breakdown clarifies how material formulation choices contribute to the overall market dynamics.
