Physical properties of the different three layers particleboards A.
Table 4 shows the results of physical properties of three-layer particleboards and single-layer control panels. Apart form the control boards, Type 1 panels had the lowest thickness swelling and water uptake values; 36% and 117%, respectively. Types 2 and 3panels ranked next. This shows that panels having high ratios of RW particles on their surfaces possess exhibited lower TS and WA values than the boards having low ratios of RW particles.
