Wood Flour Extraction Improves Moisture Performance of Wood-Plastic Composites
Snapshot: Improving the moisture performance of wood-plastic composites provides a potential avenue toward improving the product's overall durability. Forest Service scientists evaluated methods for pre-treating the wood flour before incorporation into the plastic matrix as a strategy to improve composite performance. Extractions and delignification were performed on the wood flour, and it was demonstrated that solvent extraction of the wood flour has the potential to significantly improve composite performance.
This research will improve the durability of wood-plastic composite deckboards such as the one shown here being evaluated for color. Nicole Stark, USDA Forest Service
