“…It should be noted that there is still no report on the preparation of TPVs based on these polymeric materials. [19][20][21][22][23] This research is thus aimed to explore the effect of SSA-LDH concentration on crosslinking density, compression set, morphological, thermal, mechanical, rheological, and gel content properties of crosslinked PUR/PP-based TPV. Also LDH nanoparticles are non-toxic and eco-friendly materials with conspicuous features like facile and affordable synthesis and powerful ion-exchange ability which leads to a promoted compatibilization between the rubber and polymeric phase of a TPV component, However, no report has addressed the application of this nano material on the synthesis of a TPV component.…”

Herein, a novel polypropylene/polyurethane rubber (PP/PUR) was prepared based on thermoplastics vulcanizates (TPV)/layered double hydroxide (LDH) nanocomposite in the presence of 3-(triethoxysilyl)propylsuccinic anhydride (SSA) intercalated LDH (SSA-LDH). The effect of SSA-LDH was explored on thermo-mechanical, thermal, morphological, rheological, and mechanical properties as well as gel content, compression set, X-ray photoelectron spectroscopy analysis, and cross-linking density (CLD) of TPV based on PP/PUR with the weight ratio of 40/60. It was found that the crystallization, tensile strength, gel content, cross-linking density, young’s modulus, elongation at break, melting point, and damping factor significantly changed with increasing SSA-LDH content in PUR/PP TPVs. The reasons could be attributed to cross-linking induced by SSA-LDH and curing agent Bis-(triethoxysilylpropyl) tetrasulfide (also called (Si-69)) that grafted onto PUR chains, resulting in good dispersion of fine PUR vulcanized particles into PP matrix. This claim was confirmed by studying the rheological properties through Rheometeric mechanical spectroscopy and dynamic-mechanical analysis. Field emission scanning electron microscope images confirmed the improved compatibility between PUR and PP by adding SSA-LDH. The gel content and CLD of TPV samples without SSA-LDH were 20% and 2.75 mol/mL, respectively, which showed a significant increment to 25.5% and 4.5 mol/L upon adding 5 wt. % SSA-LDH. The highest elongation at break, tensile strength, and young’s modulus were 525%, 16.5 MPa, and 210 MPa, respectively which were observed for TPV5.

“…Also, Hidaya et al [25] reported that the DBS of LLDPE/SR loaded with Si, BN, and Zn nanofillers are better in all blended formulations relative to the related compositions without nanofillers. Dutta et al [34] studied polyethylene octene elastomer/ethylene-vinyl acetate copolymer (POE/EVA) reinforced with organoclay particles. The findings revealed that the nanocomposite containing 0.5 wt% of organoclay showed an improvement in the breakdown voltage value from 6 kV to 10 kV.…”

Silicone rubber (SR) and ethylene-propylene-diene monomer (EPDM) are widely-used polymers as housing for high voltage insulators. In this work, SR/EPDM/clay nanocomposites were obtained by two-roll mill mixing for outdoor polymeric insulators. Morphology, dielectric properties, dielectric breakdown strength (DBS), and surface and volume resistivity of different weight contents of nanoclay (Cloisite 15A) incorporated in SR, EPDM, and SR/EPDM hybrid nanocomposites were characterized. In addition, the distribution of breakdown voltages was fit to the distribution of Weibull and estimated the scale and shape parameters. The polar groups of the clay particles enhanced the polarization capability of the nanocomposites. Moreover, DBS results showed an enhancement of the dielectric strength proportional to clay content. Finally, the surface and volume resistance of all nanocomposites decreases but maintains very high electrical resistance. The experimental data presented in this study will be useful for designing and manufacturing the outdoor insulators.

“…Researchers have extensively studied the inuence of these factors on the mechanical, elastic, and rheological attributes of TPVs, aiming to optimize their performance for specic applications. [2][3][4] TPVs have gained signicant popularity as the fastestgrowing elastomers in recent years due to their ability to replace unrecyclable thermoset rubbers. This characteristic aligns with the increasing emphasis on environmental protection and resource conservation.…”
