WPC decking is crafted by blending wood fibers (such as sawdust or wood flour) with thermoplastic polymers, typically polyethylene (PE), polypropylene (PP), or polyvinyl chloride (PVC). These materials are mixed together with additives like colorants, stabilizers, and lubricants. The mixture is then processed through extrusion, injection molding, or compression molding techniques to form various decking profiles. This unique manufacturing process results in a composite material that mimics the appearance of real wood while offering enhanced performance.
