The brominated phenol-formaldehyde resin was investigated as plywood adhesive in order to study the effect of bromine on physical and flammability properties of this resin. The effect of bromine content in brominated phenol-formaldehyde resin as plywood adhesive was studied. This research involves the use of this adhesive for preparation of 3-ply plywood from rubber wood veneer. Compressing temperature and compressing time were varied in preparation process. Flammability and resistance to cold and hot water of plywood samples were studied. Result of this study showed that brominated phenol-foromaldehyde resin of 10% bromine content by wt. of phenol-formaldehyde resin was suitable to be used as plywood adhesive. The optimum parameters for plywood preparation were compressing time of 30 min and compressing temperature of 110 ํC. Prepared plywood using brominated phenol-formaldehyde resin as adhesive under the optimum conditions gave moisture content 9.64%, shear strength 266.97 N/cm2, flame retardancy property which was studied by the limiting oxygen index value (LOI value) 27.16% and good resistance to cold and hot water. The plywood with brominated phenol-formaldehyde adhesive demonstrated that brominated phenol-formaldehyde resin could be used as plywood adhesive.
