and TiO 2 nanoparticles are dispersed, and can find the appropriate applications for their advanced properties, substituting existing products made from different rubbers and plastics, offering significant economic benefits to companies. The elastomer was dynamically cross-linked in the plastomer matrix, during processing, by classic vulcanization system with sulfur and accelerators. Accelerators used, namely tert-butyl-2-benzothiazyl sulphenamide - Vulkacit NZ and benzothiazyl-2-dicyclohexyl sulphenamide - Vulcacit DZ. The crosslinking method is ecological, without release of aromatic nitrosamines, which are carcinogenic in the crosslinking process. Obtained composites were physical-mechanical characterized by standard methods specific to plastics. In addition to high temperatures resistance, these materials are antimicrobial, characteristic to be tested biologically.
