Evaluation of Various Fire Retardants for Use in Wood Flour/Polyethylene Composites
Snapshot: Wood-plastic composites (WPCs) represent a class of materials increasingly used in residential construction and furniture-making. The fire performance of WPCs is not well understood, however, and there is little information regarding the effectiveness of various fire retardants in the public domain. FPL scientists used oxygen index and cone calorimeter tests to characterize the fire performance of wood flour-polyethylene composites, and compared the results with unfilled polyethylene and solid wood.
