Physical and Mechanical Properties of Mediumdensity Fibreboards Using Soy-Lignin Adhesives

Emission of formaldehyde from wood-based composites is a serious concern for research. In this study, nine different combinations of soyâ��lignin-based adhesives were prepared by varying their pH and soy content. Lignin was extracted from rubberwood fibres by an enzymatic treatment. Physical and che...
