in this study, the possibility of producing wood-plastic panels was studied using two different blending methods including melt blend and dry blend. wood-plastic panels were made from recycled high density polyethylene (as resin) and mdf waste (as natural fiber) at 60, 70 and 80% by weight filler loading. nominal density and dimensions of the panels were 1g/cm3 and 35×35×1 cm, respectively. the...

nowadays, polymer blends usages increase more and more in order to produce materials with better properties. according to many research works, the blends of polyolefins have shown industrial importance. the purpose of this project was to carry out some investigations on fibers melt spun from the polypropylene and low density polyethylene blends. pp and ldpe are immiscible. pp/ldpe blend filamen...

polycaprolactone (pcl) and poly(butylene terephthalate) (pbt) blend was prepared by melt processing. the pcl/pbt blend showed similar morphology with that of pure pcl.the crystallization temperature of pcl was increased by the incorporation of pbt. it was also observed that the peak height in the dsc thermograms decreased and then disappeared by adding 40 % or more pbt which might be due to the...

Polycaprolactone (PCL) and poly(butylene terephthalate) (PBT) blend was prepared by melt processing. The PCL/PBT blend showed similar morphology with that of pure PCL.The crystallization temperature of PCL was increased by the incorporation of PBT. It was also observed that the peak height in the DSC thermograms decreased and then disappeared by adding 40 % or more PBT which might be due to...

In the past two decades, the repair and reconstruction of musculoskeletal tissues using biodegradable scaffold materials has emerged as one of the most promising approaches in tissue engineering. The aim of this study is to process, via hot melt extrusion, the biodegradable and biocompatible polymeric materials; poly(ethylene oxide) (PEO), poly(ethylene glycol) (PEG), ⍺lactose monohydrate and p...

High impact polystyrene (HIPS)/corn starch blends were prepared in presence of glycerol as a plasticizer via melt extrusion process by a twin-screw extruder. The novelty of this work is first, because of the use of pre-gelatinized corn starch as modified one and second, the procedure of making blends by extruder which makes it ease of access and also industrially possible. The blends were then ...

We have examined the structure formations in symmetric blend films of polystyrene and poly(methyl methacrylate) during phase separation and coalescence in the melt. We qualitatively verify the principle of time–temperature superposition by observing morphology development in which characteristic structures develop independently of annealing temperature and initial morphology. Domain structures ...

Fabrication of nanocomposites from immiscible polymer blend system has been represented in this work. A new type of natural clay named Halloysite Nanotubes (HNTs) are modified by Polyethyleneimine (PEI) and these PEI grafted HNTs are incorporated into the immiscible blend system during melt mixing process to prepare halloysite based nanocomposites. Fourier Transform Infrared Spectroscopy (FTIR)...

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,...
