The Sherwood-Frost constitutive model is widely used to predict the mechanical behavior of polymer materials, and it a very important material model. In this study, stress-strain curve high-density polyethylene (HDPE) with strain rate ranging from 935 5450 s−1 was obtained through split Hopkinson bar test device. Based on HDPE dynamic performance test, method for determining strain-rate paramet...

The data reported in this paper are complementary to the characterization of 4-(phenylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (AzO-TEMPO) and of the 4-(2-thienylazo)-benzoyl-2,2,6,6-tetramethylpiperidine-1-oxyl radical (ThiO-TEMPO) before and after their grafting to two polyethylene matrices (a copolymer ethylene/α-olefin (co-EO) and a high density polyethylene (HDPE)). Partic...

Recycling and reusing plastic waste are key options for ameliorating its negative effects on the environment economy. This paper proposes evolutionary polynomial regression (EPR) as a powerful technique to predict compressibility behavior of sand high-density polyethylene (HDPE) mixtures. In investigation, series large-scale oedometer experiments were conducted. The results coefficients lateral...

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 ...

Abstract In this study, we evaluate the thermal and mechanical properties of materials based on polypropylene (PP), high-density polyethylene (HDPE), terephthalate (PET) using thermogravimetric analysis impulse excitation technique. The results show that even if melted input material together with pressure ~4 MPa was used to produce samples, can find small cavities around sand grains in samples...

Fiber-reinforced polymer (FRP) is the most promising technique in present era to bring sustainability, reliability, and pseudo ductility concrete structures due its superior properties. Thermoplastic thermoset polymers are thrown-out synthetic waste that contributes environmental pollution for a long time. Knowing this issue an attempt was made use High-Density Polyethylene Fiber (HDPE) fillers...

Hydrosilane-B(C6F5)3 adducts were found to activate zirconocene dihalides and generate ternary catalytic systems possessing moderate to high activity in ethylene polymerization to high density polyethylene (HDPE). The activation efficacy of the adducts increased with increasing hydride donor ability and decreased with steric crowding of the particular hydrosilane used. NMR investigation of the ...

The base polymer properties have been developed experimentally by adding small amounts of different fillers but they are expensive to the polymer material. Thus, it has been investigated that the incorporation of cost-less nanoparticles like clay and fumed silica nanoparticles into low density polyethylene LDPE and high density polyethylene HDPE which controlled the breakdown strength and volta...

For the ALMA production test receivers at present being designed in the NRAO CDL, there is a need for infrared filters to reduce the thermal loading. One possibility is to use a plastic material which has reasonable absorption or scattering for the infrared wavelengths but low loss at the signal wavelengths. Black polyethylene (polyethylene with carbon filler) [1, 2], Zitex (expanded PTFE) [3],...

Climate change occasioned by the accumulation of greenhouse gases (GHGs) is now widely accepted as an issue which mankind needs to address. The starting point is necessarily the determination of all the sources of emissions during the life-cycles of the studied components. Post-calculation, the results ought to be presented to decision-makers in a clear manner so as to provide the basis on whic...
