the percentage of wood will also have a bearing on the strength and stiffness of the product. generally speaking, the more wood that's added, the stiffer the product becomes. wood can make up as much as 70% of the total wood-plastic composite, but the resulting stiffness comes at the expense of the ductility of the final .
