Polymers have tremendous applications from household to high technology applications. The polymers are easy to produce, light, and flexible. However, mechanical properties of polymers, in some industries, is a point of its weakness. Therefore, a mineral, as a bulk filler, was used to overcome this limitation and to reduce the cost of polymer composites and their manfacturing. In this study, the silica flour was introduced into the polypropylene (PP) matrix to enhance its mechanical properties. In addition, the styrene-ethylene/butylene-styrene (SEBS) triblock copolymer and its grafted maleic anhydride (SEBS-g-MA) were used as silica/ PP compatibilizers. The results showed an improvement in mechanical properties after the addition of silica to the PP matrix. However, silica addition led to drop in strain measures. On the other hand, the addition of the compatibilizer enhances the interfacial bonding and smoothen the transfer of the stresses between filler particles and the polymeric matrix.

Polimery znajdują szerokie zastosowanie od przedmiotów użytku domowego do aplikacji technologicznych. Polimery są łatwe w produkcji, lekkie i elastyczne. Jednakże, mechaniczne właściwości polimerów są niewystarczające w pewnych przemysłowych zastosowaniach. Dla tego, sproszkowane materiały są wprowadzane jako wypełnienie. Pozwala to na pokonanie wspomnianych ograniczeń i zredukowania kosztów wytwarzania rzeczy z plastiku. W przedstawionych badaniach, mączka kwarcowa była dodawana do propylenu dla podwyższenia jego mechanicznej wytrzymałości. Dodatkowo, trój-blokowy polimer (styren-etylen/butylen-styren i anhydryt maleinowy (SEBS-g-MA) były użyte jako odczynniki łączące krzemionkę z PP. Otrzymane wyniki wskazują na poprawę właściwości mechanicznych po dodaniu krzemionki do matrycy polimerowej (PP). Jednakże, nadmierne dodanie krzemionki prowadzi do zmniejszenia naprężenia. Odwrotne działanie mają odczynniki łączące. Powodują one intensyfikację wiązań ich zwiększenie oraz niweluje naprężenia między cząstkami wypełniacza a matrycą polimerową.
