Effect of filler carbonization on agro-waste based ceiling board

This work presents the use as a filler of carbonized breadfruit seed coat and recycled low density polyethylene binder in ceiling board manufacturing. The depulped bread fruit was for 2 h at temperature 500°C. experimental design set up using Design Expert software. A total 30 tests were developed four parameters three responses. are coat/recycled Low Density Polyethylene mass ratio (filler-binder ratio), compaction time, pressure while responses thermal conductivity, thickness swell water absorption. models have been validated Study Variance (ANOVA). Using 3D surface map, influence on studied. optimization method program used to evaluate optimal level that will produce best possible result from their combination. gave values 16.206% filler/rLDPE, 9.406minutes 200°C 11 MPa pressure, which 0.246% Water Absorption, 1.998% Thickness Swell 2.898 W/M.K Thermal Conductivity.
