Characterization of plywood made from heat-treated rubberwood veneers bonded with melamine urea formaldehyde resin

Abstract The objective of the study is to evaluate properties plywood made from rubberwood veneers thermally treated at various temperatures. Rotary-peeled were 160, 170, 180, and 190 °C under 1 bar pressure. 5-ply panels produced using melamine urea formaldehyde (MUF) resin as binder. Dimensional stability, i.e., water absorption (WA) thickness swelling (TS) well mechanical assessed. results demonstrated that dimensional stability improved indicated by lower WA TS values. reduction in values increased along with treatment Darkening a result heat was observed. Meanwhile, 170 180 resulted highest modulus rupture (MOR), elasticity (MOE) shear strength. However, beyond temperature, strength started decline. Based on findings this work it appears temperatures ranging 160 could have potential improve overall panels.
