The effects of paper sludge (PS) and kaolin on properties of PP/EPDM composites were examined. The mechanical properties, morphology. water absorption, and thermal properties were investigated. At a similar filler loading, PP/EPDM/kaolin composites show higher mechanical properties (such as tensile strength and elongation at break. except Youngיs modulus), lower water absorption, and better thermal stability compared to PP/EPDM/PS composites. However PP/EPDM/PS composites exhibit better
Youngיs modulus and percentage of crystallinity than PP/EPDM/kaolin composites. SEM of tensile fracture surfaces of composites show that the PP/EPDM/kaolin composites
have better filler dispersion and filler-matrix interaction than PP/EPDM/PS composites.
