Due to high filler loading, clean, commercial, thermoplastic, flame-retardant materials are mechanically unstable when insulating wires and cables. In this study, composite formulations of linear low-density polyethylene (LLDPE)/ethylene-vinyl acetate (EVA) containing a flame retardant, such as magnesium hydroxide (MH; formula: Mg(OH)
Abstract Recent attempts toward improving the properties of natural rubber (NR) by using carbon nanotubes (CNT) as filler were not successful due to low dispersion CNT in NR. This article reports results studies on improvement NR acid modification surface. Fourier transform infrared spectra confirmed presence COOH groups On basis differential scanning calorimetry, universal testing machine, dynamic mechanical tester, thermogravimetric analysis, electrical properties, and transmission...
Because of their high filler loadings, commercial-grade clean flame-retardant materials have unstable mechanical properties. To address this issue, intumescent polymers can be used to develop flame retardants with very low levels smoke and toxicity generation. An retardant (IFR) system composed red phosphorus (RP), zinc borate (ZB), a terpolymer ethylene, butyl acrylate, maleic anhydride (EBM) was prepare EVA (ethylene-vinyl acetate) EVA/LLDPE (linear low-density polyethylene) composites;...
Purpose This study aims to develop a film dosimeter composed of 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MMT) dye and polyvinyl butyral (PVB) binder reduce the effect if relative humidity during irradiation. Design/methodology/approach The films were exposed gamma ray radiation from 60 Co source with 8.6 kGy/h dose-rate 1.25 MeV beam energy various doses ranging 2.5 100 kGy. UV-VIS spectrophotometer was used measure changes in optical properties irradiated by means...
Abstract This paper reports the results of studies on effect phenol functionalization carbon nanotubes (CNTs) mechanical and dynamic properties natural rubber (NR) composites. Fourier transform infrared spectrometry (FTIR) indicates characteristic peaks for ether aromatic rings in case functionalized CNT. Although differential scanning calorimetric (DSC) show no changes glass‐rubber transition temperature ( T g ) NR nanocomposites due to surface modification CNT, marginal shifting higher...
Imidazole based amphiphilic ionic liquids (ILs) were used as surfactants in miniemulsion polymerization (MEP) of styrene using a free radical process well reversible addition–fragmentation chain transfer (RAFT). Monodisperse polystyrene (PS) nanoparticles obtained, demonstrating the efficiency IL surfactant MEP. stabilized was furthermore to prepare magnetic (MNP). A large increase possible MNP content associated with very good colloidal stability achieved RAFT mediated MEP where carboxyl...
Abstract Formulations of chemically crosslinked and radiation‐crosslinked low‐density polyethylene (LDPE) containing an intumescent flame retardant such as ammonium polyphosphate were prepared. The influence blending LDPE with a poly(ethylene vinyl acetate) copolymer (EVA) the effects various coadditives, including grafted maleic anhydride (PEgMA), silane boric acid, talc, on mechanical thermal properties investigated. Chemical crosslinking by dicumyl peroxide ionizing radiation from...
Polyvinyl alcohol (PVA) of two molecular weights was used to prepare shape memory polymers based on chemical-crosslinking by glutaraldehyde. The done in the presence 2-carboxyethyl acrylate oligomers (CEA) and nano-filler [multi-wall carbon nanotubes (MWCNT) functionalized (MWCNT-NH2)] followed radiation-induced crosslinking. analysis material revealed an increase gel fraction a significant reduction swelling nanocomposite that crosslinked with both glutaraldehyde ionizing radiation....
