Thermoplastic elastomer based on LLDPE and EMA

Abstract

The effect of organoclay as well as controlled dicumyl peroxide (DCP) curing on the morphology and physicomechanical properties of linear low-density polyethylene (LLDPE)/ethylene-co-methylacrylate (EMA) blends was explored in this article. The nancomposites were melt-compounded in an internal mixer, HAAKE RHEOMIX, at 140°C and a rotor speed of 60 r min−1. The nanocomposites were then cured in a compression mold at 170°C for 12 min, and their morphology and physicomechanical properties were evaluated. Exfoliated morphology was observed for DCP-treated nanocomposites. DCP initiated grafting between polymer and clay platelets resulted in high degree of reinforcement in all nanoclay-filled samples through exfoliation of clay platelets as well as interfacial cross-linking and controlled cross-linking in the two polymer phases. Reprocessability studies showed that LLDPE/EMA/Cloisite®20A nanocomposites cured with DCP up to 0.5 wt% can easily be reprocessed.

Role of formulation additives on the properties of thermoplastic polyether ester elastomer-based and carbon fabric-reinforced multilayer composites

“…In order to improve mechanical, electrical and thermal stability properties of TPEE; fillers such as carbon black (CB), 11 talc, 12 wollastonite, 13 montmorillonite, 14 alumina trihydrate, 15 clays, 16 mica, 10 silica, 17 fly ash, 18 and kaolin 19 have been added to the polymer matrix. Pandey et al produced nanocomposites with a thermoplastic polyester elastomer and graphene oxide (GO) by using the solution mixing method.…”
