In this study wheat straw was taken from Ankara province. In order to produce dry process MDF, urea formaldehyde resin was used at the ratio of 8 %, 10 % and 12 %, 1 % ammonium chloride was used as hardening agent on the basis of dry fiber weight. On the other hand, 5, 6 and 7 min. pressing times were applied. Alcohol benzene, cold water, hot water and 1 % NaOH solubility of wheat straw were 5.15 %, 7.31 %, 9.84 % and 40.79 % respectively. In addition, holocellulose, cellulose, lignin and ash contents were found as 74.79 %, 52.67 %, 20.17% and 4.21 % respectively.
