AB  - An experimental study of high-density polyethylene (HDPE) composites filled with 
      talc (0-15 wt.%) was carried out to investigate the rheological properties. The 
      apparent melt viscosity, melt density, and die-swell ratio (B) of the composites 
      were measured at constant shear stress and constant shear rate by using a melt 
      flow indexer and capillary rheometer. The experimental conditions were set to a 
      temperature range from 190 to 220  degrees C for both apparatuses whereas a load range 
      from 5 to 12.16 kg was selected for melt flow indexer and shear rate range from 1 
      to 10000 s(-1) for capillary rheometer. The initial study showed that the talc 
      particulates did not influence the melt viscosity compared with the neat HDPE but 
      decreased the elasticity of the polymer system. The HDPE/talc systems obeyed 
      power-law model in shear stress-shear rate variations and were shear thinning, 
      meanwhile, the die-swell increased with an increased wall shear rate and shear 
      stress. The melt density of the composites increased linearly with an increase of 
      the filler weight fraction and decreased with the increase of the testing 
      temperature. The talc-HDPE composites showed compressible in the molten state.
