Dynamic Mechanical Analysis of Injection Molded Untreated and Treated Talc-filled High-density Polyethylene Composites

摘要

The mechanical properties above glass transition temperature of untreated and silane-treated injection-molded talc-filled high-density polyethylene(HDPE)composites have been studied using dynamic mechanical analysis(DMA)in the range of 0.5 to 25 Hz at 298 to 353 K.The silane treatment of the filler as well as the injection process induce a structure,resulting in inhomogeneity and anisotropy for the molded discs.Differential scanning calorimetry(DSC)is used to justify the macroscopic properties measured with DMA.
