Medium-density fiberboard (MDF) is a wood-based composite primarily manufactured using Urea-formaldehyde adhesive to bond wood fibers. There are different factors which have direct effects on MDF properties including the adhesives system, hot-pressing conditions, and wood fiber characteristics (Xing et al. 2006, Wood Sci Technol. 40. 637-646). There are few studies focusing on MDF fiber characteristics and quality; which are the main goals of this research. In this presentation, water chemistry of MDF fiber including the measurements of weak acid and phenol groups, buffering capacity, pKa values relate to different fiber acid groups, and also surface charge of the MDF fibers are shown. The specific surface area data of the fibers which was measured using BET (Brunauer-Emmett-Teller) method is also provided. All the collected data are compared to unrefined wood for the purpose of seeing the refining effect.
