Compounding of the materials was carried out in the Data Processing Plasticorder Model (PL-2003) with a single screw extruder attachment. The mixing was carried out by keeping the temperatures of the feed zone, compression zone, and metering zone as 160,170, and 180°C, respectively, at 30 rpm screw speed.The compounded materials were extruded through a strand die, and the extrudates were pelletized. The loading of wood flour was varied from 0 to 40% by weight of filler. Then, the pelletized material was mixed with 1 phr of azo di carbamide, and the foamed square sheets of 10 x 10 x 0.66 〖"cm" 〗^3 were taken out in injection molding machine. Three different types of wood flour/polymer foamed composites were prepared: untreated wood flour (UWF), maleic anhydride-treated wood flour (MWF), and PPgMA/woodflour (MPP).
