| Summary: | In thisstudy, poly vinyl chloride (PVC)/ sepiolite composites were produced using anextruder. Two different sepiolite powders: white and gray were added to the PVCin order; 5 wt.%, 10 wt.%, 15 wt.% and 20 wt.%. The morphology alteration,chemical behavior and mechanical properties of the powders and the compositeswere examined by X-ray fluorescence (XRF), tensile test, X-ray diffraction(XRD), Fourier transform infrared spectroscopy (FTIR), scanning electronmicroscopy (SEM) and ultimate tensile strength (UTS). The results showed that thesepiolite white powder had 20.72 wt.% CaO and approximately half of the 20.81wt.% SiO2 as compared to the sepiolite gray powder. The XRD analysis confirmedthat the structure of calcined white sepiolite contained dolomite, while gray calcined-sepiolitecontained zeolite. The composites with 5 wt.% sepiolite white or gray powdersexhibited higher tensile strength. Increasing the quantity of both sepiolitepowders in the composites deteriorated the surface with cracks and shifted the thermaldegradation of the sepiolite gray toward higher temperatures. |
