Particleboard is composite panel product consisting of cellulosic particles of various sizes that are bonded together with a synthetic resin or binder under heat and pressure Particle geometry, resin levels, board density and manufacturing processes may be modified to produce products suitable for specific end uses At the time of manufacture, additives can be incorporated to impart specific performance enhancements including greater dimensional stability, increased fire retardancy and moisture resistance The American National Standard for Particleboard (ANSI A208.1) is the North American industry voluntary standard - it classifies particleboard by density and strength and covers physical, mechanical and dimensional characteristics as well as formaldehyde levels
