Polymer Nanocomposites PE / PE-G-MA / EPDM / Nano Zno Dynamically Vulcanized with Peroxide

Nanocrosslinked elastic-plastic nanocomposites are blends that economically combine, in a highly advanced way, the properties of at least two polymers (elastomer and plastomer) and nanoparticles in a single product. In these mixtures the elastomeric phase is cross-linked in the thermoplastic melt under conditions of thermodynamic technology. This paper presents the development of multiphase elastic-plastic polymeric nanocomposites, dynamically vulcanized, reinforced with nanoparticles for products used in food and pharmaceutical domain, a new variety of composite material based on elastomer (ethylenepropylene-ter-polymer rubber EPDM) and nanofiller (ZnO) dispersed in the plastomer matrix (high density polyethylene-HDPE). By nanometric dispersion in plastomer matrix, elastomers and nanofiller have led to obtaining a high-performance polymer material with multifunctional characteristics (rubber and thermoplastic) and processing properties specific to plastics. Also, the elastomer was dynamically cross-linked in the plastomer matrix, during processing, by classic vulcanization system with peroxide. The crosslinking method is ecological, without release of aromatic nitrosamines, which are carcinogenic in the crosslinking process. Experimented composites were physico-mechanically characterized by standard methods specific to plastics.
