HYPEROPHASIC POLYPROPYLENE AND EPDM RUBBER COMPOSITIONS WITH THE INCORPORATION OF POLYPROPYLENE WASTE AND ARTIFACTS

摘要

HYPEROPHASIC POLYPROPYLENE AND EPDM RUBBER COMPOSITIONS WITH THE INCORPORATION OF POLYPROPYLENE WASTE AND ARTIFACTS. Heterophasic polypropylene and EPDM rubber compositions are described with the incorporation of PP residue in the ratio of 40 to 60% by weight of PP residue in the composition. The compositions are obtained by extrusion and molded into artifacts whose mechanical properties are evaluated. For their properties, the compositions of the invention are useful in the automobile industry, including the manufacture of automotive bumpers.
