Maleic anhydride-modified polypropylene was compounded with commercially available surface-modified montmorillonite in a twin-screw extruder. Recompounding ensured the removal of visible tactoids from the extrudate but TEM and XRD techniques showed nonuniform dispersion of clay platelets. In this study, we investigated the mechanical and fracture properties of nanoclayfilled polypropylene. Emph...

A Clextral BP-10 (type BC45) co-rotating twin-screw extruder was used for texture modification of extrudates. Dry materials were mixed in a mixer for 15 min at low speed before extrusion. Moisture content 21–23% and addition of soya bean flour (0–40%) showed significant influences on the texture of the extrudates. Addition of soya bean flour in the range from 0 to 40% increased the diametrical ...

The studies on wollastonite reinforced recycled ABS (Acrylonitrile butadiene styrene) composites were investigated. Powder-based with a particle size of 13 microns was mixed Acrylonitrile styrene in various proportions wt.%. Recycled homogeneously and composite prepared using twin-screw extruder it pelletized. specimens the injection moulding process mechanical properties like tensile strength ...

Tensile and impact test samples of ultra-high molecular weight polyethylene (UHMWPE), high-density (HDPE), their blends at various UHMWPE/HDPE ratios were prepared via compression molding injection for thermal, rheological, mechanical characterization. A twin-screw extruder with either a tapered die air-cooling or regular was used to compound extrude the materials prior pelletization molding. T...

The purpose of this study was to evaluate the performance of synthetic magnesium aluminometasilicate (MAS) as a novel inorganic carrier in hot melt extrusion (HME) processing of indomethacin (IND) for the development of solid dispersions. A continuous extrusion process at various IND/excipient blend ratios (20%, 30% and 40%) was performed using a twin-screw extruder. Physicochemical characteriz...

• Reclaimed nanoclay from oil-based drilling fluid waste used as nanofiller in polyamide 6 composites. Improvement interfacial adhesion between OBMFs and PA6 displaying material tailorability for significant increase mechanical properties. Storage modulus of with 10 wt% was 56% higher than that neat PA6. Clear circular economy demonstration on raw materials recovery reuse fluids management stra...

Well dispersion or intercalation/exfoliation of nanoscale fillers (such as nano-CaCO3 and nano-clay) in polymer matrix is currently not easy to be achieved. Supercritical carbon dioxide (ScCO2) has been reported to have great potential for facilitating the dispersion or intercalation/exfoliation of the nanoscale fillers in polymer matrix. So, in this paper, the effects of dissolved ScCO2 on the...

Rheological behavior of high-density polyethylene (HDPE)-wood flour composites with different wood contents was examined using steady shear sweep, oscillatory frequency sweep, creep test, and stress relaxation test. The samples were prepared using a melt compounding method in a twin-screw extruder. The results showed that the yield stress did not appear for the composites prepared under the pro...

To improve the nutrient-density of snack products, milk proteins (casein, whey protein concentrate or whey protein isolate) and wheat xber were co-extruded with corn meal your, in a twin screw extruder under high shear and high temperature processing conditions. Co-extruding corn products and xber resulted in the reduction of specixc mechanical energy while increasing the expansion and breaking...

The poly(lactic acid)/ethylene methyl acrylate copolymer (PLA/EMA) blends were melt blended with by a twin-screw extruder. The phase morphologies, mechanical, and rheological properties of the PLA/EMA blends with three weight ratios were investigated. The results showed that the addition of EMA improves the toughness of PLA at the expense of the tensile strength to a certain degree. All the PLA...
