Abstract
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.
