this paper presents an investigation on the effect of temperature and raw material on microstructure of fine cellular foam used as the insulation of coaxial cables. a set up was prepared and used to produce fine cellular foamed insulation. as the physical  blowing agent, butane was used. the effect of temperature on the microstructure of polyethylene (pe) was worth to note. at high temperature,...

A novel wood flour (WF)-filled composite based on the microfibrillar high-density polyethylene (HDPE) and Nylon-6 co-blend, in which both in situ formed Nylon-6 microfibrils and WF acted as reinforcing elements, was successfully developed using a two-step extrusion method. At the 30wt.% WF loading level, WF-filled composite based on the microfibrillized HDPE/Nylon-6 blend exhibited higher stren...

SIGNIFICANT FINDINGS: Polyethylene dispensers emitting an equilibrium blend of codlemone plus isomers were shown to be very effective in disrupting male CM orientation to virgin female-baited traps. The level of disruption achieved with these dispensers was significantly better than with Isomate C+ dispensers. These results were in contrast to our 1998 study where the disruption of 1.0 and 10.0...

Polymer White-light-emitting devices WPLEDs with single layer structures are fabricated by the spincoating method. The device structure used here is indium-tin-oxide(ITO)/polyethylene dioxythiophene(PEDOT:PSS)/polymer blend/Ca/Al, whose blend consists poly N-vinylcarbazole(PVK) hole transporting host polymer, an electron transporting materials 2-4-biphenylyl-5-tert-butylphenyl1,3,4-oxadiazole(P...

This study reports an application of instrumental color measurement for quantifying and comparing the optical properties of high density polyethylene HDPE and low density polyethylene LDPE blend films and the effect of blending ratio and miscibility on these properties. The technique of spectrophotometry in transmission and reflectance modes can be used as a versatile tool to evaluate the color...

The aim of this investigation was to develop a novel multifunctional co-processed diluent consisting of microcrystalline cellulose (Avicel PH 102), crospovidone (Polyplasdone XL) and polyethylene glycol 4000. Colloidal silicon dioxide and talc were also incorporated as minor components in the diluent to improve tableting properties. Melt granulation was adopted for preparation of co-processed d...

Blends based on recycled high density polyethylene (R-HDPE) and recycled poly(ethylene terephthalate) (R-PET) were made through reactive extrusion. The effects of maleated polyethylene (PE-g-MA), triblock copolymer of styrene and ethylene/butylene (SEBS), and 4,40-methylenedi(phenyl isocyanate) (MDI) on blend properties were studied. The 2% PE-g-MA improved the compatibility of R-HDPE and R-PET...
