Abstract

Due to rapid increase in consumption rate of EPDM in rubber industry in the last decade, recycling and reusing of this rubber have attractive and extensive studies. Blending with the other polymers can be an efficient method for reusing of recycled EPDM. In this study, TERNARY BLENDs of polypropylene (PP), high density polyethylene (HDPE) and mechano-chemical DEVULCANIZED EPDM (D-EPDM) were prepared using a laboratory twin-screw extruder. Three levels of D-EPDM (20, 40, 60 wt%) at constant concentration of HDPE (20 wt%) were used. Sulphur dynamic vulcanization was applied on the samples. MECHANICAL PROPERTIES such as: tensile properties, compression set, hardness, impact resistance and MORPHOLOGY of samples
were studied and compared to samples containing virgin EPDM. Tensile strength and compression set decreased with increase in both D-EPDM and EPDM content in the TERNARY BLEND. Dynamic vulcanization improved the MECHANICAL PROPERTIES and its effect on the samples containing D-EPDM was more onsiderable. The dominant MORPHOLOGY of both TERNARY BLENDs was the separate dispersion of HDPE and EPDM (or D-EPDM) in the PP matrix. The D-EPDM formed droplets dispersed in PP matrix similar to the virgin EPDM.
