Medium density fibreboards (MDF) were made from thermomechanical (TMP)
and chemo-thermo-mechanical pulps (CTMP) derived from pine wood. As a
binder a melamine reinforced urea formaldehyde resin (UF-resin) and d
iisocyanate polymers (PMDI) were applied. The mechanical-technical pro
perties of the boards as well as some of their chemical properties wer
e evaluated. The results of the investigation led to the following con
clusions: MDF from CTMP showed in general higher mechanical properties
(bending strength) compared to MDF from TMP. Moreover, the formaldehy
de release of the CTMP-boards was lower. This may be due to the formal
dehyde scavenging properties of the used pulping chemicals during the
process of CTMP.
