- Abstract
- More than 80 exploratory experiments were made on the development of fire retardant treated particle board using 15 fire retardant chemicals, 3 resin binders, 2 species of wood, and various types of application. Among the types of application were those employing solutions of fire retardant salts sprayed on gree flakes; and others employing dry, finely divided fire retardants added after mixing binder resin and flakes. Of the boards produced and tested, several using certain borates, AWPA Type C and Type D fire retardants, and monoammonium phosphate showed promise. Properties considered were flamespread, smoke production, strength, and stability. Salts applied in solution to gree wood, followed by drying, gave results superior to those obtained from the use of dry fire retardant salts. None of the boards were tested for fire retardant and strength after cycling through changing humidities. The results of this series of experiments are released in the form of a progress report for use by others engaged in similar studies.
