Abstract In response to the continuous demand for industry progress and need low-cost alternative materials that have superior properties than present ones, a new coupling agent was used treat composites, which were as backing in ultrasonic array transducers. transducers, back-echo reverberation piezoelectric elements occurs, so are critical reducing these echoes. The Cu–Al–Zn-alloy treated wit...

Abstract Nanocomposites based on acrylonitrile butadiene rubber (NBR) and ethylene–proplene diene monomer (EPDM) (50/50) filled with different concentrations of nano-waste magnetic filler (nWMF) up to 120 phr were prepared by two laboratory roll mill mixer. nWMF was characterized using XRD, TEM VSM. The nanocomposites investigated techniques: SEM, TGA, DSC. In addition the rheological, mechanic...

Few of today’s EPDM (electronic product data management) systems make use of valuable approaches in user interface design and information visualization as suggested by researchers. In this paper, we describe a design approach addressing the problems of searching, browsing, visualizing and filtering information in hierarchically structured graphs. The main problem areas we identified are the amo...

Ethylene-propylene-diene rubber (EPDM) is a elastomer widely used in common industrial applications. EPDM can be shaped into sheets and employed as isolating material for roofing systems. In this study, scraps of from commercial, residential systems were treated by combined thermo-mechanical microwave devulcanization processes including peroxide benzoyl (BPO). The devulcanized (Dev-EPDM) was ch...

nanocomposite samples based on elastomer blends of butyl rubber (iir) and ethylene propylene diene monomer (epdm) were prepared using a laboratory scale two-roll mill in order to study the effect of cloisite 15a organoclay content (i.e., 1, 3, 5 and 7 wt%) on the mechanical and morphological properties  of  iir/epdm/cloisite  15a  nanocomposites  compared  to  the  unflled epdm/iir blends. rheo...
