Itaconic acid – grafted – LDPE as compatibilizer for LDPE – plasticized Tapioca starch blends
Reactive and Functional Polymers, 2008LDPE has been blended with plasticized Tapioca starch with starch loadings varying from 20% to 50%. As the starch loading increases, the mechanical properties reduce and drop down to nearly 30% of that of neat LDPE. In order to enhance the adhesion between starch and LDPE, itaconic acid (naturally obtained during fermentation of sugars) was grafted ...

Applied Radiation and Isotopes, 2012
In this paper a series of low-density polyethylene (LDPE) blends with different percentages (10%, 20%, and 30%) of EVA and sets of low-density polyethylene sheets were prepared. This set consists of four subsets, which were made under different cooling methods: fast cooling in liquid nitrogen, cooling with cassette, exposing in open air, and cooling in

Investigations of environmental stress cracking resistance of LDPE/UHMWPE and LDPE/EVA blends
Plastics, Rubber and Composites, 2015Low density polyethylene (LDPE)/ultrahigh molecular weight polyethylene (UHMWPE) and LDPE/poly(ethylene-co-vinylacetate) (EVA) blends were tested and compared with respect to their environmental stress cracking resistance (ESCR) using the Bell telephone test.

Space charge behavior in multi-layered dielectrics with LDPE and LDPE/MgO nanocomposites
2010 10th IEEE International Conference on Solid Dielectrics, 2010Space charge distributions were investigated in multi-layered dielectric films consisting of combinations of low-density polyethylene (LDPE) and its nanocomposite (NC) with MgO nano-fillers during application of a dc electric field of 100 kV/mm at room temperature and 50 °C. At 100 kV/mm, a packet-like charge appears in LDPE, but not in NC.

Abstract Copper/low density polyethylene (LDPE) composites covered with LDPE film on the surface were prepared for intrauterine contraceptive device (IUD). Cu 2+ release rates of the composites were determined by absorbance measurements. The surface characteristics of the composites after incubated for 5 months were investigated by SEM and EDX ...

Electrical treeing in LDPE nanocomposite materials
2009 IEEE Conference on Electrical Insulation and Dielectric Phenomena, 2009This work deals with the inception and the growth of electrical treeing inside different Low Density Polyethylene (LDPE) nanocomposites. Two nanoflllers were adopted: sepiolite and montmorillonite. Both nanoflllers belong to the family of silicate clay minerals but have different aspect ratio. The nanocomposites have been prepared by melt dispersion of
