Abstract

The objetive of this research was to evaluate the effect of heating temperature of the logs, presessing time and pressing temperature on the glue line strength of Pinus teada phenolic plywood. A factorial analysis was applied for the different treatments showing that the best heating temperature was 60ºC and the best pressing temperature 145ºC, pressing time 9 minutes. Veneers and playwood produced at these showed the propertied.
