AB  - The aim of this study was to apply waste wood particles (WP) with different sizes 
      from primary wood processing as a filler for open-cell PUR foams. For this 
      purpose, various wood particle sizes were added as a filler for polyurethane 
      foams (PUR). The effects of the addition of of 0.05-<0.125 mm, 0.125-<0.315 mm, 
      0.315-1.25 mm, and >1.25-2.0 of WP to the polyurethane matrix on the density, the 
      kinetics of PUR foaming, the cell structure, and the morphology were 
      investigated. Scanning electron microscope (SEM) and X-ray computer tomography 
      were used. Based on the results, it was found that the addition of WP in the 
      amount of 10% leads to an increase in density with an increase in particle size. 
      The research shows that the morphology of the PUR-WP foam is influenced by its 
      particle size. The difference in the number and size of cells in PUR-WP 
      composites depends on the wood particle size. The addition of dust causes the 
      formation of cells of much smaller sizes; confirmed by SEM images. Moreover, 
      computer tomography clearly demonstrates that the WP are well-dispersed within 
      the foams' structures.
