    • Eggshell, a new bio-filler for polypropylene composites 
      Toro, P.; Quijada Abarca, Juan; Yazdani-Pedram Zobeiri, Mehrdad; Arias, José Luis (ELSEVIER SCIENCE BV, 2007-09)
      Chicken eggshell (ES) is an industrial byproduct containing 95% calcium carbonate, and its disposal constitutes a serious environmental hazard. Different proportions of chicken eggshell as bio-filler for polypropylene (PP) ...
    • Influence of grafted polypropylene on the mechanical properties of mineral-filled polypropylene composites 
      Toro, P.; Quijada Abarca, Juan; Peralta, Ronald; Yazdani-Pedram Zobeiri, Mehrdad (JOHN WILEY & SONS INC, 2007-02-15)
      The purpose of this work was to study how mineral fillers would behave in a polypropylene (PP) matrix when PP modified with maleic anhydride (MA) and/or itaconic acid (IA) was used as a coupling agent in the preparation ...
    • Mechanical and morphological studies of poly(propylene)-filled eggshell composites 
      Toro, P.; Quijada Abarca, Juan; Arias, José Luis; Yazdani-Pedram Zobeiri, Mehrdad (MACROMOLECULAR MATERIALS AND ENGINEERING 292(9): 1027-1034, 2007-09-14)
      Poly(propylene) (PP) composites were prepared by using eggshell (ES) as filler and their mechanical properties were compared with those using talc (TA) and calcium carbonate (CC) of different grain sizes (X-50). A decrease ...
    • Study of the morphology and mechanical properties of polypropylene composites with silica or rice-husk 
      Toro, P.; Quijada Abarca, Juan; Murillo, O.; Yazdani-Pedram Zobeiri, Mehrdad (JOHN WILEY & SONS LTD, 2005-04)
      The mechanical, morphological behavior and water absorption characteristics of polypropylene (PP) and silica, or PP and rice-husk, composites have been studied. The silica used in this study as filler was a commercial type ...
