Abstract:The thermal conductivities and thermal diffusivities of High-density polyethylene(HDPE)and isotactic polypropylene(PP)blends were investigated in the following percentages of HDPE by weight:0,20,40,50,60,80,100 by the Transient Plane Sourceby(TPS).The thermal conductivities appeared to be independent of the injection conditions,and a linear relation can solely be drawn with the HDPE content.Nevertheless,in spite of the fact that the thermal diffusivities could be influenced by the processing variables,it ca...
