Optimization of Toughness and Stiffness in Wollastonite Filled Polypropylene

Some mineral filled composites, based on polypropylene heterophasic copolymers and wollastonite, were produced to investigate on the optimization of mechanical properties. It was shown that a new crystalline portion would be developed in the bed of PP indicating on a special nucleating capability of wollastonite; and its fraction could be extend by a slight presence of polyethylene. Such alteration in semi-crystalline structure of the matrix induced an important enhancing effect on the toughness of the composites
