Abstract:

MAH-g-polyethylene (PE)/neat PE/ wood-flour composites were prepared by extrusion. The influence of the content of MAH-g-PE and wood-flour on the water absorption of the composite was studied. Kept the weight ratio of MAH-g- PE/neat PE constant, the water absorption decreased with decreasing wood-flour content. At high wood-flour loading, the higher the content of MAH-g-PE, the lower the water absorption. The lower the water absorption, the higher the wet mechanical properties.

Key words: polyethylene, wood-plastic composites, water absorption, mechanical properties
