The article presents the results of research on the influence of selected technological parameters, changed within a range similar to values presently used in industry, on the properties of three-layer particleboards produced from pine particlesobtained from sawmill waste. The particles were glued with amine resins. The panels, produced using urea-formaldehyde resin modified with melamine, were characterisedby the lowest content of formaldehyde, i.e. below 2 mg/100 g of ovendry board, after conversion into a value corresponding to the moisture content of the panels equalling 6.5%. The emissions of formaldehyde determined by the chamber and gas analysis methods were much lower than the threshold values recommended in international regulations and used as a basis for the classification of particleboards.
