  1. Hot water extracted wood fiber for production of wood plastic composites (WPCs)

    Undebarked ponderosa pine chips were treated by hot water extraction to modify the chemical composition. In the treated pine (TP) , the mass was reduced by approximately 20%, and the extract was composed mainly of degradation products of hemicelluloses. Wood flour produced from TP and unextracted chips (untreated pine, UP) was blended with high-density polyethylene (...

  2. A review of wood thermal pretreatments to improve wood composite properties

    The objective of this paper is to review the published literature on improving properties of wood composites through thermal pretreatment of wood. Thermal pretreatment has been conducted in moist environments using hot water or steam at temperatures up to 180 and 230 ˚C, respectively, or in dry environments using inert gases at temperatures up to 240 ˚...
