Impact of Resin Content on Swelling Pressure of Three Layer Perticleboard Bonded with Urea-Formaldehyde Adhesive

When particleboards are exposed to water or moist environment, they tend to swell and expand in all directions. The degree of swelling or expansion depends on the type of adhesive used, its share, and the time of exposure and pressure used at hot pressing. The expansion of particleboard, exposed to...
