Wood-plastic composite - Wikipedia

Wood-plastic composites (wpcs) are composite materials made of wood fiber/wood flour and thermoplastic(s) In addition to wood fiber and The ratio of wood to plastic in the composite will ultimately determine the melt flow index (MFI) of the wpc, with larger amounts of wood generally leading to a lower MFI. Wood plastic Another major selling point of these materials is their lack of need for paint.
