The effect of varied proportion of Aluminum Trihydrate [Al (OH)3] on the rheological properties of Wood Plastic Composites produced from Eucalyptus camaldulensis was investigated in this study. Wood Plastic Composites were produced at varied Al (OH)3 proportions of (0, 5, 10, 20, 30 and 40) % to polymer and wood weigh respectively. Rheological properties such as maximum torque, steady state of torque, processing temperature and maximum processing energy attained were investigated on the composite samples produced respectively.
