ABSTRACT
This research was developed aiming to evaluate the potentiality of soy bean, rice flour, maize flour, oatmeal and manioc flour, as alternative extenders to wheatmeal for plywood manufaturing. Twenty one boards were produced using Eucalyptus cloeziana venner, being three boards per treatment according to the following formulation in parts per wheight: urea-formaldheyde resin - 100, extender - 75, water - 80 and catalyst - 7. The average values of shear bonding tests (dry and wet), showed that the ricemeal and oatmeal could be used as an alternative extender to the wheatmeal.
