The effects of Nanoprecipated Calcium Carbonate (NPCC) particles on the mechanical properties of Poly (vinyl chloride), PVC were investigated. Besides than that, the aim is to compare the experimental data with theoretical predictions. To produce the blends, PVC resins and various additives was dry blended using a laboratory blender before being milled into sheets on a two on a two-roll mill. Then the test specimen were hot pressed and compressed moulded for tensile test. Six various compositions of blend, 5, 10, 15, 20, 25 and 30 phr were prepared. The mechanical properties, morphology and thermal analysis were studied by using Tensile Test, Fourier Transform Infrared (FTIR), Scanning Electron Microscopy (SEM) and Differential Scanning Calorimetry (DSC). The result showed improvement in tensile strength at NPCC content of 5 phr. But, tensile strength for PVC/NPCC was then decreased with increasing amount of NPCC. YoungÂ’s Modulus of PVC/NPCC increased withincreasing NPCC content. Elongation at break of PVC/NPCC composites can be greatly increased even at low content of NPCC. The modulus curve showed good agreement with Guth Â–Smallwood while tensile strength curve showed good fit with the two thirds power law. From SEM, it is observed that the surface look was rougher with the higher loading of NPCC. A slight increase in Tg with addition of NPCC was observed. This was predictable since incorporation of NPCC increased the YoungÂ’s Modulus.
