The aim of this study is to determine some properties of oriented particle boards (OSB) produced by using urea formaldehyde (UF) resin produced different formaldehyde/urea ratios. For this purpose, boards that dimension 2440 x 1220 x 11 mm were produced with resins which has different formaldehyde/urea ratio in a local board facility. After the produced boards were cut to dimensions in accordance with the standards, its trials were carried out in accordance with TS EN standards. When the results are examined, average density of the boards produced with glue with 1,250 mol ratio is 596 kg/m³, the average thickness swelling value for 24 hours is 26.3%, average of the density of the boards produced with glue with 1.10 molar ratio is 603 kg/m³, the 24-hour thickness swelling value is average value was measured as 25.9%. There was no significant difference in the bending strength values longitudinally and transversely to the production direction and the internal bond strength values of the samples. Free formaldehyde value of the boards produced with the resin having 1.250 molar ratio is 14.1 mg/100g, free formaldehyde value of the boards produced with the glue having 1.10 molar ratio is 7.01 mg/100g.
