Low-density polyethylene (LDPE) is an important thermoplastic material which can be made into films, containers, wires, cables, etc. It highly valued in the fields of packaging, medicine, and health, as well cables. The method improving dielectric property materials by blending LDPE with inorganic particles filler has been paid much attention researchers. In this paper, low-density used matrix,...

It is estimated that 60 to 70% of LLDPE enters the market as blends (Utracki 1989a), primarily with other members of the polyolefin family, e.g., LDPE or polypropylene (PP). Despite the long history of polyethylene (PE) blending and its widespread use, many questions about the homogeneity of such blends, with obvious implications for thermodynamics and for the rheology, are still not answered t...

Polyethylene exhibits many key characteristics including low dielectric loss, high breakdown strength and good processability. Most modern extruded high voltage cables employ cross-linked polyethylene (XLPE) as the insulation material. The main advantage of XLPE is its excellent thermo-mechanical properties; it is relatively cheap and has low dielectric loss and low conductivity making it an id...

The modified atmosphere packaging technique was explored in order to investigate the changes of passion fruit quality during low temperature storage. Three different types of packaging condition were used in this experiment. They were (i) P-UAP, a perforated low density polyethylene (LDPE), (ii) MAP-1, a LDPE with an oxygen transmission rate (OTR) of 1400016000 cm3/m2∙day∙atm, and (iii) MAP-2, ...

Garbage is one of the complex problems faced by both developing and developed countries in world. Waste processing continues to be Indonesia reduce risk environmental pollution, which existence a waste bank attract increase public awareness. One banks Pati Regency Bolo Larah Bank. Based on results surveys observations, there are several bank, including limited administration savings management ...

Observations are reported in isothermal torsional oscillation tests on melts of isotactic polypropylene (iPP) and low-density polyethylene (LDPE) in the intervals of temperature between 190 and 250 C (iPP) and between 120 and 190 C (LDPE). With reference to the concept of transient networks, constitutive equations are developed for the viscoelastic response of polymer melts at three-dimensional...

The influence of a typical prooxidative additive, cobalt stearate, on the thermal stability, degradation kinetics and lifetime of low-density polyethylene (LDPE) was investigated using non-isothermal thermogravimetric analysis (TGA) in both nitrogen and air atmosphere. The derivative thermogravimetric (DTG) curves indicate single stage and multistage decomposition process in nitrogen and air at...

The dispersion, morphology and crystallization kinetics of low density polyethylene (LDPE) octakis(noctadecyldimethylsiloxy)octasilsesquioxane (POSS) nanocomposite blends was investigated. Novel octakis(dimethylsiloxy)octasilsesquioxane (Q8M8) molecules were octafunctionalised with octadecyl alkyl-chains (Q8C18) and blended with 0.25-10 wt% loadings into a commercial LDPE. Time-resolved Smallan...
