Disposing of plastic wastes to landfill is becoming undesirable due to legislation pressures, rising costs and the poor biodegradability of commonly used polymers. In addition, incineration meets with strong societal opposition. Therefore, recycling either mechanical or chemical, seems to be the only route of plastic wastes management towards sustainability. Polyolefins, mainly polyethylene (LD...

The nanocavitation distribution in deformed High Density PolyEthylene (HDPE) was investigated. A flat notched sample of HDPE, under steady crosshead speed up to the end stress softening, observed by classical synchrotron parallel beam microtomography and magnified holotomography with a true spatial resolution 0.7 μm 0.05 μm, respectively. Image processing, 3D image segmentation 2D-Fast Fourier ...

The mechanical properties of polyethylene (PE) materials are greatly influenced by their molecular structures, environmental temperature, and strain rate. In this study, static dynamic compression tests were performed on two semicrystalline PE materials—ultrahigh weight (UHMWPE) high-density (HDPE). stress–strain curves HDPE UHMWPE under uniaxial at temperatures −40–120 °C rates 0.001–5500 s−1 ...

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...

It is a challenge to identify each phase in multi-component polymer system and uniquely determine the interfacial properties between different phases. Using atomic force microscopy nanomechanical mapping (AFM-NM) AFM-based infrared spectroscopy (AFM-IR), we phase, visualize structural developments, blend of three polymers: high-density polyethylene (HDPE), polyamide (PA6) poly(styrene-b-ethylen...

The present study investigates the effects of oxalic acid and 1-methylcyclopropane (1-MCP) treatments in combination with low-density polyethylene (LDPE) high-density (HDPE) on post-harvest storage litchi fruits. physicochemical properties, bioactive compounds, antioxidant activities, dismutase enzyme activity (SOD) treated untreated fruits were examined during 30 days at 4 ℃. most effective wa...

Among many lightweight materials used in marine applications, sandwich structures with syntactic foam core are promising because of lower water uptake amid face-sheets damage. HDPE (high-density polyethylene) filament is to 3D print skin, and glass microballoon (GMB) reinforced filaments for the core. The optimized parameters prepare blends 20, 40, 60 volume % GMB HDPE. These foamed extruded fo...

The aim of this study is to investigate the kinetic characteristics high-density polyethylene (HDPE) waste pyrolysis process based on thermogravimetric analysis (TGA) and using a fixed bed pyrolytic reactor (FBPR) at different temperatures. In addition, influence material thickness yield distribution composition products was examined over temperature range 425–550°C. A higher wax fraction obtai...

Abstract Six biofilm carriers with different polymer were studied in fixed-film systems under anoxic conditions. Different media of polymers influence wastewater treatment performance. The aim this study was to investigate polymeric materials, polyethylene terephthalate (PET), polyvinyl chloride (PVC), polypropylene (PP), high-density (HDPE), and polymethyl methacrylate (acrylic), that affect b...
