Production of particle boards with Bolaina (Guazuma crinita Mart) from a four-year-old plantation. Three-ply particle boards, 12 mm thick and 0,65 g.cm-3 of density, were made using wood (Guazuma crinita Mart), "bolaina", from a fouryear plantation located in Neshuya Ucayali. The particles were glued with a formaldehyde urea. The physical and mechanical properties of the boards were evaluated according to the methodology proposed by the European Standards for each test. The values of the specific mass and pH of the wood are suitable for the manufacture of particle boards, swelling without paraffin at 2 and 24 hours of immersion in water was 26,45% and 36,40% respectively with paraffin at 2 hours the swelling decreased by 5.29% however at 24 hours of immersion in water the swelling increased by 1.88%. The mean static bending without paraffin was 15.55 MPa, a value close to that found with paraffin. The internal bond without paraffin was 0.97 MPa with a decrease of 15.46% when using paraffin. The evaluation of the results obtained shows that it is possible to manufacture particle boards use with 4-yearold bolaina.
