By adjusting the species, size and concentration of wood particles in the formulation, different properties can be achieved. wood-plastic composites can even be foamed to make a strong lightweight material. Similarly, the chosen wood
Over a dozen processors already foam wood-fiber composites and an equal number are experimenting with it. Tri-Ex makes this three-layer hollow profile for railings using 10% wood-filled foam core between solid unfilled pvc skins.
We've discussed factors of wood-plastic composite that affect design, but what about during the processing phase of plastic During foaming, extrusion and injection molding, wood-plastic composites are compatible with existing machinery.
foaming of wood-fiber/ plastic composites (WPC) with a fine-celled structure can offer benefits such as improved ductility and .. foamed rigid pvc/wood-flour composites and the moisture content of the wood flour, the chemical foaming agent
