In this study, medium density fiberboard panels were produced by adding different ratios of some
amine compounds to urea formaldehyde resin, which had 1:1.17 mol ratios. The formaldehyde
contents, physical, and mechanical properties of medium density fiberboard panels were determined
according to EN standard methods.
In this study, it was determined that the formaldehyde emission emitted from medium density
fiberboard panels decreased by adding urea, propylamine, methylamine, ethylamine, and cyclopentylamine
solution. It was found that the water absorption and thickness swelling values increased
slightly; however, the internal bond strength, modulus of rupture, and modulus of elasticity of medium
density fiberboard panels also increased substantially, but these properties of medium density
fiberboard panels decreased by adding higher ratios of urea solution. It was found that the
formaldehyde emission of medium density fiberboard panels decreased 16.5% by using a 16% rate of
urea formaldehyde resin and 0.8% rate of urea and ethylamine solution. These decreases were
determined as 57% for cyclopentylamine solution addition, 41% for propylamine solution addition,
and 48% for methylamine solution addition
