The UK Dairy Roadmap has set a target of achieving 50 wt.-% high density polyethylene (HDPE) recyclate in their HDPE milk bottles. Such content will lead to the accumulation recyclates that have been subjected different number melt extrusion cycles supply chain. This work investigates structure-property relationship blending virgin (vHDPE) with these grades repeatedly melt-extruded (rHDPE). was...

nanocomposite vulcunizates based on styrene-butadiene rubber (sbr), organoclay and a conventional sulfur curing system were prepared by melt blending process in an internal mixer. in order to study the effects of the type of interfacial compatibilizer on the properties of sbr and clay nanoparticles,three types of compatibilizers, maleic anhydride grafted ethylene-propylene diene rubber (epdm-g-...

Polyamide-6 (PA-6)/graphite nanocomposites were prepared by melt blending, using a variety of graphites, including virgin graphite, expandable graphites and expanded graphite. The resulting nanocomposites were characterized by X-ray diffraction, thermogravimetric analysis, cone calorimetry, and tensile mechanical analysis. Nanocomposite formation does occur, as denoted by the nanometre dispersi...

Abstract. The magnetic properties of magnetite nanoparticles and magnetite-thermoplastic natural rubber (TPNR) nanocomposites was prepared by melt-blending method has been studied using vibrating sample magnetometer (VSM). The saturation magnetization (MS), remanence (MR), squareness (MR/MS), coercivity (HC) and exchange-bias field (Heb) for magnetite nanoparticles and its nanocomposites increa...

We report the linear increase in the glass transition temperature, Tg, with nanofiller weight content. ZnO quantum dots dispersed by melt-blending in a poly(methyl methacrylate) host were characterized by differential scanning calorimetry and dynamic mechanical analysis showing that the Tg of the system is described by a power law of the interparticle distance, hp, where the percolation exponen...

Nowadays polymer nanocomposites have introduced as a new class of food packaging materials due to their enhanced mechanical, thermal, and barrier properties. In this study PET nano composites were prepared by melt blending of poly (ethylene terephthalate) pellets and mica nanoparticles. The morphology of PET/mica nanocomposites was characterized by X-ray diffraction and transmission electron mi...

Two types of graphene-nanoplatelets (GNP-M and GNP-C) were incorporated in PLA (poly(lactic acid)) by melt blending. Materials were biodegraded during 6 months and characterized by XRD, tensile tests, DMA and biocompatibility assays. For both fillers, low loadings (0.25 wt.%) improved mechanical properties and decreased their decay until 6 months biodegradation. PLA degradation decreased its to...

This paper focuses on the fabrication via simple melt blending of thermotropic liquid crystal polyester (TLCP) nanocomposites reinforced with a very small quantity of modified carbon nanotube (CNT) and the unique effects of the modified CNT on the physical properties of the nanocomposites. The thermal, mechanical, and rheological properties of modified CNT-reinforced TLCP nanocomposites are hig...
