Feasibility of utilizing polypropylene as a binder for plywood manufacture

In this study, plywood manufacture with use of polypropylene as a binder has been studied. The variables were polypropylene in three levels of 80, 120 and 160 g/m2 and maleic anhydride polypropylene coupling agent in two levels of 0 and 4 g/m2 . ureformaldehyde and wheat flour were used for contr...
