DYNAMICALLY CURED POLYMER COMPOSITE BASED ON PP AND EPDM FOR THE FOOTWEAR INDUSTRY
Journal Title: Revista de Pielărie Încălţăminte - Year 2015, Vol 15, Issue 2
Abstract
The aim of this paper is to obtain a dynamically cured polymeric composite based on polypropylene and ethylene-propylene-diene-terpolymer rubber, compatibilized with polypropylene-graft-maleic anhydride and added crosslinking agents (dicumyl peroxide). Performance of polymeric structures depend on the concentration and morphology of the elastomer and plastomer used, processing parameters, type and concentration of auxiliary materials used in compounding and of course, on the equipment and working parameters. The polymeric composite was made using the extrusion-granulation technology, so that it could be processed by molding and electrical pressing, at the optimum processing parameters. The resulting polymeric composite was tested in terms of its physical-mechanical properties (normal state and accelerated ageing at the temperature of 70°C, for 168 h) and structural properties, employing appropriate techniques.
