The mechanical properties, dimensional stability, and sound absorption ability of MDF panels manufactured with developed foam-type urea-Formaldehyde (UF) resin adhesives were investigated. The cure characteristics of resins were determined by differential scanning calorimetry analysis (DSC), and the reined fibers and the porosity of the MDF panel were observed by SEM. MDF panels prepared with A foam-type UF resin had better mechanical properties and dimensional stability, even better than control MDF panels. However, there was no significant difference in sound absorption ability among panels. DSC analysis revealed that A foam-type UF had a lower onset and peak temperature and a slightly sharper peak curve. In addition, it was observed by SEM that much more A foam-type UF resin adhesive agglomerated on the fiber surface, exhibiting better foaming effect, and that the porosity of the MDF panel was reduced, further confirming the foam effect.
