Abstract (EN):
The aim of this work is to develop a PF resin for wood-based panels production that satisfies
formaldehyde emission restrictions and LEED criteria. The effect of small changes in
condensation pH was tested in order to optimize the mechanical performance and formaldehyde
emissions. In this work particleboard production was also optimized, by changing blending
conditions and pressing times.
The results showed that a higher amount of base added in the condensation step results in better
mechanical performance. On the other hand, higher amounts of catalyst will result in better
performances for different pressing times.
The best performing resin obtained in this study showed very good values for internal bond
strength and formaldehyde content, making appropriate for use in the so-called “Green Building”
construction.
