The effect of controlled dicumyl peroxide (DCP) curing on the rheological behavior of linear low density polyethylene (LLDPE)/ethylene methyl acrylate (EMA)/Closite®20A nanocomposites were investigated under dynamic and steady shear flow (in a capillary) conditions. The nancomposites were melt‐compounded at 140°C, by varying the sequence of addition and amount of Cloisite®20A and DCP. The nanocomposites were cured in a compression mold at 170°C for 12 min. Both the cured and uncurednancomposites showed non‐Newtonian behavior and the elastic response of both cured and uncurednanocomposites increases with increasing frequency. The activation energy of flow for LLDPE/EMA/Closite®20A nanocomposites was increased with increasing DCP content. DCP‐cured nanocomposites exhibited shorter relaxation time than uncured nanocomposites. The die swell values are well correlated with relaxation results. POLYM.

“…Hosier et al investigated crystallization behaviour, morphology, and dielectric breakdown of LDPE/EVA blends with high EVA content. Hui et al conducted a series of studies on LDPE/EVA filled with nanosilica focusing on the effect of nanofiller concentration and electron beam irradiation on various properties including thermal, electrical and rheological properties. Recently, Mahmoudi et al developed an insulation material based on HDPE/EVA/organoclay which can be employed to insulate the adjacent core steel sheets of a high voltage transformer.…”

Thermoplastic elastomer (TPE) has gained acceptance as third generation of polymeric materials for high voltage (HV) insulators. The interesting features showed by TPEs were found to fulfill some particular requirements for HV insulations, at least for the distribution class applications, especially at light contamination environments. Introduction of nanomaterials which widely reported to give significant improvements in the electrical, mechanical, thermal and other properties of polymer has attracted attention to the synergistic properties of combining the two complementary technologies of thermoplastic elastomers and nanocomposites. In this paper, research works on various types of TPEs having promising performance as HV insulators are thoroughly reviewed. The emergence of nanocomposites in the electrical insulation field and the important properties consideration for HV insulators as well as the processing techniques of TPE nanocomposites are also discussed. Finally, some of the past and recent developments of TPE nanocomposites focusing on the electrical insulation properties are highlighted in this article. POLYM. ENG.

“…Irradiation is very powerful form of energy which can produce deep changes in the polymers. Crosslinking via controlled irradiation is an alternative to dynamic vulcanization to improve the properties of thermoplastic elastomers (TPEs) considerably 20. One of the advantages of irradiation crosslinking is that it can be done on finished products at room temperature.…”

Ethylene-octene copolymer (EOC) was irradiated using electron beam irradiation at different dosages (30, 60, 90, and 120 kGy). Effect of irradiation dosage on thermal and mechanical properties was studied. When compared to low density polyethylene, EOC exhibited higher degree of crosslinking reflected in increased gel content, higher elastic modulus (G 0 ), and lower tan d obtained by rheology measurement at 150 C. Crosslinking caused improvement in high-temperature creep and room temperature and also elevated temperature elastic properties. Differential scanning calorimetry revealed that e-beam irradiation has caused a gradual reduction in crystallinity and a presence of a fraction with higher melting temperature. In the case of EOC, as the extent of crosslinking increased, stress at break showed an increasing trend whereas irradiation dosage had an inverse effect on elongation at break. Radiation dosage has positive effect on thermal stability estimated by thermogravimetric analysis. After 30 min of thermal degradation at 220 C, slightly higher C¼ ¼O peak for crosslinked sample was found by Fourier transform infrared spectroscopy while for room temperature samples no C¼ ¼O peak was detected.
