Effect of acetylated wood flour or coupling agent on moisture, UV, and biological resistance of extruded woodfiber-plastic composites

Although moisture sorption in woodfiber-thermoplastic composites (WPCs) is slower than in unmodified solid wood, it still affects strength and ultimately results in decay of the material in moist outdoor exposure conditions. Chemical modification of the hydroxyl groups of wood with acetic anhydride esterifies the hydroxyl making the wood more hydrophobic and...

Durability of wood-plastic composites

Deterioration is broadly defined as any negative effect on the properties of a material. The effects can be due to biological attack or to various non-living agents (sunlight, moisture, temperature), but often, deterioration results from a combination of factors. Nowhere is this more evident than with WPCs, owing to the marriage of dissimilar materials. This article...
