This research studied the effect of polyvinyl acetate emulsion adhesives (PVAcEA) on the impact resistance and water absorption of plywood from a dry grass powder (DGP). The plywood was prepared using dry grass powder mixed with polyvinyl acetate emulsion adhesives at 1:0.2, 1:0.4, 1:0.6, 1:0.8, 1:1 of DGP:PVAcEA ratio and formed a plywood with a hydraulic press machine at 170 °C of temperature for 10 minutes. The impact resistance was tested according to ISO 7765-1:1988, and water absorption was measured according to ASTM D570-98. It was found that the impact resistance increased, and water absorption decreased with the increase of polyvinyl acetate emulsion adhesives. The DGP: PVAcEA ratio at 1:1 showed the highest impact resistance and lowest water absorption.
