In order to search whether or not the kaolin ratio was one of the crucial reasons influenced on the durability of Poplar Plywood utilizing outdoor which was adhesive by phenol-formaldehyde resin. Xenon Lamp Climate Chamber process and ASTMD1037 Six-cycle method were evolved in this study to measure the durability of the plywood. There was no relativity between the kaolin ratio and the durability of the Poplar Plywood. The main factor impacting the endurance property of the Plywood was the degradations of veneer and Phenol-Formaldehyde resin caused by environmental change. The kaolin filling ratio of Phenol-Formaldehyde adhesive is not able to reduce the durability of the Poplar Plywood. Under the two method treatments, the bonding strength of the laminate wood still fulfills the Plywood GB/T17657-1999 National Stander even the ratio of kaolin is in high-level. Therefore, it is a preferable choice to adopt kaolin as filling in phenol-formaldehyde.
